Abstract
The measurements of production and properties of heavy flavoured hadrons can be used to probe our understanding of quantum chromodynamics and to search for physics beyond the Standard Model.This paper summarises three recent results from the ATLAS experiment at the Large Hadron Collider. It includes search for an exotic state X(5568) in the Bs0π± final state, measurement of quarkonia production in pPb and pp collisions and angular analysis of the rare decay B0→K⁎μ+μ−.
Highlights
The ATLAS experiment [1] at the Large Hadron Collider performs a wide range of precision measurements of the Standard Model (SM) processes and parameters and searches for hints of physics beyond the SM
The Inner Detector (ID) detects tracks of charged particles and consists of pixel, silicon strip and transition radiation subdetectors embedded in a 2 T solenoidal magnetic field
In proton-nucleus collisions, the formation of large regions of quark-gluon plasma (QGP) is not expected and changes in the quarkonium production are attributed to cold nuclear matter (CNM) effects, such as modification of parton distribution functions, parton saturation and interaction with nuclear medium or absorption of the formed quark-antiquark pair in the nuclear medium
Summary
The ATLAS experiment [1] at the Large Hadron Collider performs a wide range of precision measurements of the Standard Model (SM) processes and parameters and searches for hints of physics beyond the SM. Results presented here are based o√n dataset collected in 2011 (at centre-of-mass energy s = 7 TeV) and The presented analysis by ATLAS [6] searches for X(5568) in a decay X(5568) → Bs0π±, Bs0 → J/ψφ in a dataset from pp collisions collected in 2011 and 2012.
