First measurement of time-dependent CP violation in Bs -> K+K- decays

First measurement of time-dependent CP violation in Bs -> K+K- decays

Direct and mixing-induced CP-violating asymmetries in Bs -> K+K- decays are measured for the first time using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb^{-1}, collected with the LHCb detector at a centre-of-mass energy of 7 TeV. The results are C_{KK}...
