Measurement of $\phi_s$ in Run2 at LHCb

Two recent measurements of CP-violating parameters are presented, obtained using proton-proton collision data collected by the LHCb detector in 2015 and 2016 at a centre-of-mass energy of 13TeV. In particular, the measurement of the CP-violating phase φs using a time-dependent analysis of the $B$$_{s}$ → $J$/ψ$K$ and $B$$_{s}$ → $J$/ψ$\pi$$^{+}$$\pi$$^{-}$ channels is described.
