Measurements of the CP violating phase $\phi_s$ at LHCb

High Energy Physics - Experiment 2017-09-04 v1

Abstract

The measurement of the mixing-induced CP-violating phase ϕs\phi_s in the Bs0Bˉs0B^0_s - \bar{B}^0_s system is one of the key goals of the LHCb experiment, and provides an excellent opportunity to search for New Physics beyond Standard Model. Using Run-I data, ϕs\phi_s has been measured in several decay channels. These proceedings briefly summarise the previous LHCb Run-I results of ϕs\phi_s measurement, and show the most recent results obtained by analysing the decay channel Bs0J/ψK+KB^0_s \to J/\psi K^+ K^- in the K+KK^+ K^- mass region above the ϕ\phi(1020) resonance.
