Measurement of CP violation in B0→ D+D− and Bs0→Ds+Ds− decays

A time-dependent, flavour-tagged measurement of CP violation is performed with B0→ D+D− and Bs0→Ds+Ds− decays, using data collected by the LHCb detector in proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 6 fb−1. In B0→ D+D− decays the CP-violation parameters are measured to beSD+D−=−0.552±0.100stat±0.010syst,CD+D−=0.128±0.103stat±0.010syst.In Bs0→Ds+Ds− decays the CP-violating parameter formulation in terms of ϕs and |λ| results inϕs=−0.086±0.106stat±0.028systrad,∣λDs+Ds−∣=1.145±0.126stat±0.031syst.These results represent the most precise single measurement of the CP-violation parameters in their respective channels.

What Do Mismatch Negativity (MMN) Responses Tell Us About Tinnitus?

Due to the heterogeneous causes, symptoms and associated comorbidities with tinnitus, there remains an unmet need for a clear biomarker of tinnitus presence. Previous research has suggested a "final pathway" of tinnitus presence, which occurs regardless of the specific mechanisms that resulted in alterations of auditory predictions and, eventually, tinnitus perception. Predictive inference mechanisms have been proposed as the possible basis for this final unifying pathway. A commonly used measure of prediction violation is mismatch negativity (MMN), an electrical potential generated in response to most stimuli that violate an established regularity. This narrative review discusses 16 studies comparing MMN between tinnitus and non-tinnitus groups. Methods varied considerably, including type of deviant, type of paradigm and carrier frequency. A minority of studies matched groups for age, sex and hearing, with few measuring hyperacusis. Frequency deviants were the most widely studied; at frequencies remote from tinnitus, MMN was consistently smaller in tinnitus groups, though hyperacusis or altered distress or attention could not be ruled out as explanatory factors. Few studies have used tinnitus-related frequencies; these showed larger MMN to upward frequency deviants above the tinnitus frequency, and larger MMN to upward intensity deviants at or close to the tinnitus frequency. However, the latter appears a correlate of hyperacusis rather than tinnitus, and tinnitus groups without hyperacusis instead show larger MMN to downward intensity deviants than controls. Other factors that affect MMN amplitudes included age, attention, and the specific characteristics of the range of stimuli across a particular experiment paradigm. As such, MMN cannot presently be considered a specific biomarker of tinnitus, but showed potential to objectively characterise a number of auditory processing traits relevant to tinnitus and hyperacusis.

Optimization of leptonic CP violation search using baseline configurations in neutrino oscillation experiments

Abstract One of the fundamental goals of the neutrino program over the next decade will be to look for leptonic CP violation and precisely determine its magnitude. Neutrino oscillation measurements are frequently conducted with a near-site detector for constraining the flux and neutrino interaction models and a far-site monolithic massive detector for measuring the oscillated spectrum pattern. In this work, we present an investigation of an alternative experimental configuration to improve the CP violation measurement sensitivity by using multiple sub-detectors while keeping the overall detector mass constant and placing them at different baselines. The study makes use of neutrino beams from the T2HK, DUNE and ESSνSB experiments. It is found that the coverage of true δCP values that can be explored with ≥ 5σ C.L. improves significantly after deploying multiple far detectors, instead of the conventional single far-detector technique.

The Urgency of Regulating the Measure of Violation in Terms of Sanctioning Notary

This study aims to analyze the urgency of legal ambiguity in determining the benchmark for imposing sanctions on notaries based on the Law on Notary Positions (UUJN). The UUJN regulates various sanctions for notaries who violate the law but does not provide clear guidelines regarding the criteria for imposing sanctions. This results in legal uncertainty and inconsistency in the enforcement of sanctions, as evidenced by the different sanctions imposed on two notaries, DS and MI, despite their similar violations. This research employs a normative juridical method with a statutory approach and a case approach. The results show that the ambiguity of norms in the UUJN has the potential to cause injustice in the enforcement of sanctions, as well as disrupt legal certainty and the integrity of the notary profession. In conclusion, a revision of the UUJN or the addition of supplementary regulations that include clearer and more proportional benchmarks for sanctioning is necessary. This will ensure justice and consistency in the application of sanctions, as well as uphold the integrity of the notary profession

Measurement of CP Violation in D0 Meson Decays at the CMS Experiment

The paper describes the search results for CP violation in the D0 → decay. The analysis was performed using the proton–proton collision data with centre-of-mass energy of = 13 TeV, recorded by the CMS experiment at the Large Hadron Collider. The analyzed data sample contains about 1010 events associated with production of charm hadrons, which allows performing precise measurements. The measured CP violation parameter is ACP (D0 → ) = (6.2 ± 3.1 (stat.) ± 0.2 (syst.) ± 0.8 (ACP (D0 → π+π−))%, where the last uncertainty is due to the uncertainty in the reference channel asymmetry ACP (D0 → π+π−). The obtained results are consistent with no CP violation in the studied decay. This analysis is the first measurement of CP violation in charm sector at the CMS experiment.

Higgs physics at ILC

International Linear Collider (ILC) is a viable option for realization of a future Higgs factory. With proven accelerator technology and technically mature detector design, ILC offers well-understood physics program in the top, EW and Higgs sectors. Clean environment of electron–positron collisions, together with beam polarization of both beams and center-of-mass reach at a TeV scale, will make ILC a precision tool to probe realizations of new physics. The above will be illustrated on examples of fully simulated measurements in the Higgs sector, including Higgs couplings, Higgs self-coupling, CP violation measurements and Higgs exotic decay studies at ILC.

New approaches to the implementation of supervisory powers in capital markets and organized commodity markets

The article analyzes new mechanisms and measures of influence on supervisory entities in capital markets and organized commodity markets. A general positive assessment is given to the innovations related to the introduction of more flexible tools for adjusting the state of stock and organized commodity markets, as well as the expansion of the powers of the National Securities and Stock Market Commission (NSSMC), while simultaneously strengthening the legal guarantees of the rights of supervised entities. Attention is paid to changes regarding the inclusion of individuals as subjects of responsibility under this law, clearer delineation of the scope of supervised entities, and significant expansion of the rights of supervised entities by utilizing the best practices of regulating procedural relations between the supervisory body and the supervised entity. The article also explores the deepening regulation of communicative connections between these entities and the procedures for implementing supervisory measures. Attention is given to preventive measures for violations, such as «recommendations by inspectors» and «requests for the adoption of measures.» The article analyzes new forms of implementing supervisory powers and measures of influence on supervised entities, as well as new mechanisms for their implementation that were not previously known in domestic practice. The legal significance of «public warnings» is highlighted, and a legal evaluation of «settlement agreements regarding the consequences of violating sectoral legislation» is provided as an alternative to administrative enforcement measures. According to the authors, concluding such an agreement cannot be considered as a discretionary power of the NSSMC but rather a right of the supervised entity. Conclusions are made regarding the compliance of the introduction of «controlled services» with the IOSCO principle. Taking into account the guarantees of the rights of supervised entities, as stipulated in Article 35 of the Law of Ukraine «On Amendments to the Law of Ukraine ‘On State Regulation of Capital Markets and Organized Commodity Markets’ and Some Other Legislative Acts of Ukraine on Improving State Regulation and Supervision in Capital Markets and Organized Commodity Markets» of February 22, 2024, No. 3585-IX (hereinafter referred to as Law No. 3585-IX). The article defines the functional purpose of legislative restrictions on financial sanctions against supervised entities - legal entities, which, in the authors’ view, aim to prevent their economic destruction and the disruption of economic ties in the respective market. In conclusion, the changes introduced as a result of the adoption of Law No. 3585-IX are expected to positively impact the relationship between the regulator and market participants. The innovations in the practice of legal regulation of relations between the regulator and supervised entities deserve to be extended to other similar areas of state control and supervision.

Search for Time-Dependent CP Violation in D0→π+π−π0 Decays

A measurement of time-dependent CP violation in D0→π+π−π0 decays using a pp collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7 fb−1, is presented. The initial flavor of each D0 candidate is determined from the charge of the pion produced in the D*(2010)+→D0π+ decay. The decay D0→K−π+π0 is used as a control channel to validate the measurement procedure. The gradient of the time-dependent CP asymmetry ΔY in D0→π+π−π0 decays is measured to be ΔY=(−1.3±6.3±2.4)×10−4, where the first uncertainty is statistical and the second is systematic, which is compatible with CP conservation. © 2024 CERN, for the LHCb Collaboration 2024 CERN

MEASURES OF INFLUENCE FOR VIOLATION OF FINANCIAL MONITORING BY BANKS IN UKRAINE

The research examines the organizational principles of building a system of influence measures for violations of financial monitoring by banks in Ukraine, analysis of fines imposed on banks in the field of financial monitoring, and judicial practice of challenging the applied influence measures for the period from 2018 to 2023. This subject of research was chosen due to the impossibility of effective functioning of the national system of financial monitoring without an effective regulation mechanism. An integral part of market regulation is the implementation of influence measures adequate to the committed violation. The application of influence measures and control over the implementation of corrective actions contribute to the strengthening of the national financial monitoring system. The relevance of the study is determined by the heterogeneity of the functioning of financial monitoring systems in different jurisdictions, the involvement of a wide range of reporting entities in this process, the constant development in the field of financial monitoring due to the digital transformation of the provision of financial services. A wide list of influence measures, which the financial regulator has the right to apply to banks according to Ukrainian legislation, was revealed, including a ban on carrying out certain types of operations, removing management from their positions, classifying the bank as problematic or liquidating the bank. However, in practice, the use of influence measures in the form of written warnings and fines prevailed. The National Bank of Ukraine, as a rule, applied fines in the case of problems of banks with the implementation of measures for customer due diligence and poor banking analysis of financial transactions of clients. The ultimate goal of most schemes, which, according to the National Bank of Ukraine, violated the legislation in the field of financial monitoring, was the conversion of non-cash funds into cash. Banks appealed the decision of the financial regulator only in case of significant fines. At the same time, the courts made different decisions in similar situations, which indicates the absence of a unified position of the judicial system regarding the legality of the application of fines to banks for violations in the field of financial monitoring.

National Legislations on Air Quality Protection and Penalties for Atmospheric Air Pollution in Central Asia

Air pollution poses severe risks to public health and the environment, with acts contributing to air contamination potentially constituting environmental crimes or public health offenses. This research examines the national legislations and international legal frameworks aimed at safeguarding atmospheric air quality and addressing air pollution-related offenses in Central Asian countries. Particular attention is given to legal provisions that establish emission standards, monitoring mechanisms, and punitive measures for violations. By exploring the genesis and implementation of these legal instruments, the research identifies potential gaps, inconsistencies, or weaknesses that may hinder the effective prosecution of environmental crimes associated with air pollution in the Central Asian region. This study contributes to the broader understanding of environmental criminology by examining the interplay between international norms, national legislations, and institutional structures in combating air pollution-related offenses.

Legal regulation of labor relations in the field of labor protection supervision and control

In the field of labor law, the legal regulation of labor relations in the field of labor protection is investigated, the corresponding measures of supervision and control are characterized, which, in addition to measures for violations of the requirements of labor protection legislation, provide for measures for their prevention and prevention. It is emphasized that state management of labor protection is carried out by the Cabinet of Ministers of Ukraine, the central body of executive power that implements state policy in the field of labor protection, ministries and other central bodies of executive power, the Council of Ministers of the Autonomous Republic of Crimea, local state administrations and local self-government bodies. It is noted that the powers in the field of labor protection of associations, corporations, concerns and other associations are determined by their charters or agreements between the enterprises that formed the association. In order to perform the functions delegated by the association, labor protection services are created in their apparatuses. The theoretical provisions are substantiated and practical recommendations are developed for improving the legal regulation of labor relations in the field of labor protection based on analysis methods and a systemic approach to generalization for evaluating the effectiveness of state management mechanisms in the field of labor protection. In addition, general scientific and empirical methods and tools of the science of labor law, methods of analysis and synthesis, comparison, summary and grouping were used. It was concluded that legal regulation in the field of occupational health and safety is a multilevel and complex functional mechanism, which at all levels of executive power controls and coordinates compliance with occupational health and safety at enterprises, institutions, and organizations regardless of their ownership, types of activity, and branch affiliation. It is emphasized that the existing system of state supervision and control over labor protection in Ukraine needs to be improved and brought into compliance with European standards.

Recent CP violation and lifetime results from CMS

Recent results on CP violation in charm and beauty sector, as well as lifetime measurements, by the CMS experiment at the LHC are presented. The first measurement of CP violation in charm by CMS is reported, as well as the most precise measurement of effective lifetime $${\tau (B_s^0 \to J/\psi K_S^0)} $$ and the first evidence for CP violation in the $${B_s^0} $$ → J/ψ ϕ(1020) → μ+ μ−K+K− decay. The analyses are based on 13 TeV proton-proton collision data.

Fast Inclusive Flavour Tagging at LHCb

The task of identifying B meson flavor at the primary interaction point in the LHCb detector is crucial for measurements of mixing and timedependent CP violation. Flavor tagging is usually done with a small number of expert systems that find important tracks to infer the B meson flavor from. Recent advances show that replacing all of those expert systems with one ML algorithm that considers all tracks in an event yields an increase in tagging power. However, training the current classifier takes a long time and it is not suitable for use in real time triggers. In this work we present a new classifier, based on the DeepSet architecture. With the right inductive bias of permutation invariance, we achieve great speedups in training (multiple hours vs 10 minutes), a factor of 4-5 speed-up in inference for use in real time environments like the trigger and less tagging asymmetry. For the first time we investigate and compare performances of these “Inclusive Flavor Taggers” on simulation of the upgraded LHCb detector for the third run of the LHC.

When customers strike back: examining the impact of psychological contract violation on customers' switching behaviour

Although the psychological contract has garnered attention from scholars in the social sciences, little is known about its implications from a marketing perspective. This study aims to investigate the mediating role of customer-brand disidentification between psychological contract violation and customers' switching behaviour. It represents an initial attempt to explore psychological contract violation from the perspective of the service domain in emerging economies, contributing to theoretical and practical discussions on the factors influencing customers' switching behaviour. The study utilised a quantitative-based cross-sectional design involving 399 customers from three selected pay television companies in Tanzania's media industry. Data were collected using a structured questionnaire and analysed using structural equation modelling. The findings reveal that psychological contract violation influences customers' switching behaviour when mediated by customer-brand disidentification. Consequently, if disidentification is not managed effectively, customers disengage from their relationship with the service providers and opt for alternative providers. The study suggests that service providers should proactively identify signs of psychological contract violation and implement necessary measures to address them, thereby mitigating the likelihood of customers resorting to switching behaviour.

SIMULATION AND RESEARCH OF SINGLE-PHASE SHORT CIRCUITS IN THE ELECTRICAL NETWORK

The purpose of this work is to model single-phase short circuits in a three-phase electrical network and identify their type by analyzing the angular frequency of the spatial vector. Recently, the saturation of electric networks with powerful non-linear loads, the introduction of conversion equipment and renewable energy sources lead to the need for systematic analysis and research of the quality of electric energy (QEE). One of the factors that significantly affect the operation of electrical equipment is short circuits. In the article, based on the developed model of the formation of QEE distortions, a single-phase short circuit in a three-phase electrical network is investigated by switching it to a single-phase system with two α-β projections and a zero-sequence voltage vector.
 Studies of the influence of the location of the short-circuit point on the voltage in the electrical network have shown that the difference in the distance from the point of damage to the load, type of short-circuit leads to varying degrees of voltage change. Conducted studies have shown that different types of malfunctions and parameters of the electrical network at the point of short circuit cause different disturbances in the electrical voltage in the power supply system. The presence of a short circuit of the same type at different locations leads to different voltage drops and overvoltages. Short-term changes in voltage are the most common distortions of the quality of electrical voltage in electrical networks. The simulation results based on the developed model are consistent with the theory and reliably simulate the change in voltage in the electrical network.
 In the future, the presented model can help in creating a basis for the identification and subsequent control measures of voltage change violations.

Predicting the baryon asymmetry with degenerate right-handed neutrinos

We consider the generation of a baryon asymmetry in an extension of the Standard Model with two singlet Majorana fermions that are degenerate above the electroweak phase transition. The model can explain neutrino masses as well as the observed matter-antimatter asymmetry, for masses of the heavy singlets below the electroweak scale. The only physical CP violating phases in the model are those in the PMNS mixing matrix, i.e. the Dirac phase and a Majorana phase that enter light neutrino observables. We present an accurate analytic approximation for the baryon asymmetry in terms of CP flavour invariants, and derive the correlations with neutrino observables. We demonstrate that the measurement of CP violation in neutrino oscillations as well as the mixings of the heavy neutral leptons with the electron, muon and tau flavours suffice to pin down the matter-antimatter asymmetry from laboratory measurements.

Measurement of CP Violation in B^{0}→K_{S}^{0}π^{0} Decays at Belle II.

We report a measurement of the CP-violating parameters C and S in B^{0}→K_{S}^{0}π^{0} decays at Belle II using a sample of 387×10^{6} BB[over ¯] events recorded in e^{+}e^{-} collisions at a center-of-mass energy corresponding to the ϒ(4S) resonance. These parameters are determined by fitting the proper decay-time distribution of a sample of 415 signal events. We obtain C=-0.04_{-0.15}^{+0.14}±0.05 and S=0.75_{-0.23}^{+0.20}±0.04, where the first uncertainties are statistical and the second are systematic.

Phenomenological study of decays* *Supported by the National Natural Science Foundation of China (12175244, 11875262, 11805037, U1832121) and National Key Research and Development Program of China (2020YFA0406301)

The measurement of decay parameters is one of the important goals of particle physics experiments, and the measurement serves as a probe to search for evidence of CP violation in baryonic decays. The experimental results will aid in advancing existing theoretical research and establishing new experimental objectives. In this study, we formulate the asymmetric parameters that characterize parity violation, and then derive formulas for the measurement of CP violation. The formulae for the joint angular distribution of the full decay chain as well as the polarization observable of , , Λ, and are also provided for experiments. Lastly, we evaluated the sensitivity of two asymmetric parameters: (abbreviated as ) and (abbreviated as ) for future experimental measurements.

Earth mover’s distance as a measure of CP violation

We introduce a new unbinned two sample test statistic sensitive to CP violation utilizing the optimal transport plan associated with the Wasserstein (earth mover’s) distance. The efficacy of the test statistic is shown via two examples of CP asymmetric distributions with varying sample sizes: the Dalitz distributions of B0 → K+π−π0 and of D0 → π+π−π0 decays. The windowed version of the Wasserstein distance test statistic is shown to have comparable sensitivity to CP violation as the commonly used energy test statistic, but also retains information about the localized distributions of CP asymmetry over the Dalitz plot. For large statistic datasets we introduce two modified Wasserstein distance based test statistics — the binned and the sliced Wasserstein distance statistics, which show comparable sensitivity to CP violation, but improved computing time and memory scalings. Finally, general extensions and applications of the introduced statistics are discussed.
