First measurement of time-dependent CP violation in B0 → K+K- decays

Direct and mixing-induced CP-violating asymmetries in B0 s → 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 7TeV. The results are CKK = 0.14 ± 0.11...
