$\phi_s$ status and prospects at LHCb

Recent measurements of the time-dependent CP violation by the LHCb experiment are presented. The decays of $B_s$ mesons to $J/\psi K^+ K^-$ and $J/\psi \pi^+ \pi^-$ final states are used to measure the CP-violating phase $\phi_{s}$ in tree-dominated transitions, while $B_s^0\to(K^+ \pi^-) (K^- \pi^+...

description Recent measurements of the time-dependent CP violation by the LHCb experiment are presented. The decays of $B_s$ mesons to $J/\psi K^+ K^-$ and $J/\psi \pi^+ \pi^-$ final states are used to measure the CP-violating phase $\phi_{s}$ in tree-dominated transitions, while $B_s^0\to(K^+ \pi^-) (K^- \pi^+)$ and $B_s^0\to \phi \phi$ decay modes are used to measure the CP violating phases $\phi_{s}^{sd\overline{d}}$ and $\phi_{s}^{ss\overline{s}}$, which arise in penguin-dominated decays. The most recent status of the analyses of the four decay modes is summarised.
