| contents | Precise measurements of the $B_s^0 - \overline{B}_s^0$ 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 $ϕ_s^{c\bar{c}s}$ and $ϕ_s^{s\bar{s}s}$, 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 $B_s^0 \to J/ψϕ$ by LHC experiments. |
