Abstract: K01.00001 : Measurement of the CP-violating parameters in the Bs0->J/ψφ decay using proton-proton collision data collected by CMS at √s = 13 TeV.
2:00 PM–2:30 PM
CMS (Compact Muon Solenoid)
The question is why the universe had chosen such an asymmetric evolution? Toward answering this fundamental question in 1967 A. Sakharov proposed that Charge(C) conjugation and Parity(P) violation might have played a crucial role in the evolution of baryon asymmetry. In this talk I will discuss how a CP violating weak phase ( Φs ) can be measured in laboratory when a neutral strange bottom meson decays to muons and kaons ( Bs0->J/ψφ->μ+μ-K+K-). This measurement is performed using the data collected by the Compact Muon Solenoid Experiment based at Large Hadron Collider. The data is produced in proton-proton collision at center of mass energy √s = 13 TeV. I will go through the basic steps of the data analysis for this particular study and at the end we will discuss what would be the possible impact of such studies in future physics.
