Description

The determination of the CP-violating phase φs in B0s → J/ψφ decays is one of the key goals of the LHCb experiment. Its value is predicted to be very small in the Standard Model but can be significantly enhanced in many models of new physics. We present the world’s best measurement of φs and the first observation of a non-zero ∆Γs based on 1.0 fb−1 of data collected at LHCb during 2011. We also present a measurement of φs using the predominantly CP-odd B0s → J/ψππ decay mode. Additionally we present results on other Bs decay modes, relevant for potential future measurements of φs, such as Bs → φφ and Bs → J/ψK∗0 decays.
