Beauty to charmonium decays at LHCb
The latest results of beauty meson decays to final states with charmonium resonances from LHCb are presented. This includes measurements of time-dependent CP violation parameters in $B_s^0\to J/\psi K^+K^-$ and $B_s^0\to J/\psi\pi^+\pi^-$ decay modes. Combined with the measurements from other decay...

| Sumario: | The latest results of beauty meson decays to final states with charmonium resonances from LHCb are presented. This includes measurements of time-dependent CP violation parameters in $B_s^0\to J/\psi K^+K^-$ and $B_s^0\to J/\psi\pi^+\pi^-$ decay modes. Combined with the measurements from other decay modes, the latest world average of $\phi_s$ value is $\phi_s=(-0.051\pm0.023)~{\rm rad}$, dominated by the LHCb measurements. |
