Abstract

This proceeding contribution presents the latest measurement of the CP-violation and other physics parameters in the B_s⁰ → J/ψϕ decay channel performed by the ATLAS, CMS and LHCb experiments. The measurements are based on a data set collected at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. Besides the CP violating phase ϕ_s, the width difference between the B_s⁰ meson mass eigenstates ΔΓ_s and the average decay width Γ_s are measured. The measured values are then combined with those collected at 8 TeV. The measurements are consistent with theoretical predictions based on the Standard Model.
