Description
The one of main goals of the LHCb experiment is the measurement of the mixing-induced CP-violating phase phi_s in the Bs-Bsbar system. It has been measured exploiting the Run l data set, using several decay channels. The most recent results obtained analyzing Bs0->J/psi K+K- candidates in the K+K- mass region above the phi(1020) resonance are presented. However, the precision of phi_s is still limited by the statistics. Also the measurements using the same final state with the K+K- mass at the phi(1020) and Bs0->J/psi pi+pi-, as well as using the Bs0->Psi(2S) phi decay will be discussed.
