Summary
Mixing and CP violation have been studied by ATLAS in the
decay of Bs meson to J/psi Phi, observed in the final state
mu+mu-K+K-. The different amplitudes contributing to the process are
studied through the time dependence of the angular distribution. We
present the ATLAS latest results on the measurements of the average
lifetime and lifetime difference between the two mass eigenstates, as
well as the CP violating phase phi_s.
