Abstract

These proceedings present the current status of measurements of the CP-violating phase phisphi_s by the LHCb collaboration, reviewing the measurements in channels such as Bs0J/ψϕB_s^0\to J/\psi\phi, Bs0J/ψπ+πB_s^0\to J/\psi \pi^+\pi^- and Bs0ψ(2S)ϕB_s^0 \to \psi(2S)\phi. The observation of the Bs0ηcϕB_s^0\to\eta_c\phi decay mode is presented for the first time, which can be used to measure ϕs\phi_s with larger data samples that will be collected over the coming years by the LHCb experiment. Finally, the expected increase in precision from LHCb measurements of ϕs\phi_s over the next decade is presented.
