  • A first flavor-tagged measurement of the time-dependent CP-violating asymmetry in Bs0→φφ decays is presented. In this decay channel, the CP-violating weak phase arises due to CP violation in the interference between Bs0-Bs0 mixing and the b→sss gluonic penguin decay amplitude. Using a sample of pp collision data corresponding to an integrated luminosity of 1.0 fb
