Abstract
Recent results are summarized from the TOTEM experiment at CERN LHC, including measurements of the total, elastic and inelastic cross-sections, the nuclear slope parameter B, the differential cross-section of elastic scattering and the real to imaginary part ration ρ at $ \sqrt s $ = 2.76 and 13 TeV. The implications of these data for Odderon (odd-gluon colorless) exchange are discussed.
Highlights
Seven experiments are completing their data taking and data analysis programmes at the Large Hadron Collider (LHC), the most energetic particle accelerator made by humans so far
The four general purpose experiments, ALICE, ATLAS, CMS and LHCb are supplemented by three specialized experiments, LHCf, MoEDAL and TOTEM, that focus on forward physics and search for exotic particle states
The goal of the TOTEM experiment is to measure colorless exchange, including elastic, single and double diffractive scattering as well as central exclusive production at the energies of the Large Hadron Collider at CERN. These processes correspond to an increasing elastic fraction of the total cross-section and their precise measurement requires special experimental setup in the forward direction, in the LHC tunnel extending as far as 220 m from Interaction Point 5 (IP5), the collision point that is used for measurements by both the CMS and the TOTEM experiments
Summary
Seven experiments are completing their data taking and data analysis programmes at the Large Hadron Collider (LHC), the most energetic particle accelerator made by humans so far. The four general purpose experiments, ALICE, ATLAS, CMS and LHCb are supplemented by three specialized experiments, LHCf, MoEDAL and TOTEM, that focus on forward physics and search for exotic particle states. Five out of these seven experiments, namely ALICE, ATLAS, CMS, LHCb and TOTEM are overseen by the Resource Review Boards of LHC. This report summarizes recent results from the TOTEM experiment (TOTal cross-section and Elastic scattering Measurement), presented at the XLVIII International Symposium on Multiparticle Dynamics, Singapore, in September 2018. We quote the final TOTEM results, this manuscript can be considered as a brief summary of the results of the four most recent TOTEM publications of refs. [1,2,3,4]
