Description
A large sample (20 k) of Bs -> J/psi Phi decays were collected by ATLAS in year 2011. The transition to states with defined CP eigenvalues have been studied through angular correlations in decays of J/psi and Phi. Measurement of the lifetimes of the different eigenstates and the CP-violating mixing phase phi_s have been recently obtained and are presented.
