Description
Direct and indirect CP violation is observed in particle decays. The latter usually includes oscillations between a neutral meson and its antiparticle. ATLAS measures this type of CP violation in the decay Bs -> J/psi + phi, with J/psi -> µ+µ- and phi -> K+K-, mainly because it is sensitive to higher order effects and therefore to deviations from known physics. Here the quantity of interest is the so-called weak mixing phase phi_s. Latest results will be presented and compared to similar analyses from other LHC experiments as well as with the expectation from the Standard Model.
