Measurement of CP-violating parameters in $B^0_s \to J/\psi K^+K^-$ and $B^0_s \to J/\psi \pi^+ \pi^-$ decays at LHCb

Two recent measurements of CP-violating observables are presented, obtained studying the decays of $B^0_s$ and $\overline{B}^0_s$ mesons into $J/\psi  h^+h^-(h=\pi,K)$ final states in a data sample corresponding to 1.9 fb$^{-1}$ of integrated luminosity collected with the LHCb detector in 13 TeV pro...

description Two recent measurements of CP-violating observables are presented, obtained studying the decays of $B^0_s$ and $\overline{B}^0_s$ mesons into $J/\psi  h^+h^-(h=\pi,K)$ final states in a data sample corresponding to 1.9 fb$^{-1}$ of integrated luminosity collected with the LHCb detector in 13 TeV proton-proton collisions. In particular, the measurement of the CP-violating phase φs is described.
