Abstract

Precise measurements of the B_s⁰ - B_s⁰ mixing parameters provide a powerful test of the Standard Model, offering potential hints to new physics. The LHCb collaboration has performed updated measurements of the CP-violating phases ϕ_s^ccs and ϕ_s^sss, which supersede previous results. Also, an alternative approach to determine ΔΓ_s is presented, bringing a new tool that may help to resolve the tension observed between measurements made in B_s⁰ → J/ψϕ by LHC experiments.
