Description
The LHCb experiment focuses on CP violation, a process that explains the abundance of matter in the Universe. The Standard Model theory prediction of CP violation is much smaller than the observed asymmetry. The 'golden decay mode' B0s→J/ψφ could easily be influenced by New Physics particles, and shift the experimentally observed amount of CP violation from the theory prediction. I will present the analysis of 2015 + 2016 3fb-1 B0s→J/ψφ data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV. The talk will also cover the combination with Run 1 data, yielding the World's most precise determinations of the CP violating phase φs and of the decay width difference between the light and the heavy mass eigenstates in the B0s system.
