Abstract |
We present the latest results from the LHCb experiment on the measurement of the time-
dependent CP asymmetries in B0 → π+π− and Bs 0 → K + K − in addition to the time-integrated CP
asymmetries in B 0 → K + π− and Bs 0 → π+K − . The analysis uses a data sample of pp collisions
corresponding to an integrated luminosity of 3.0 fb−1 , collected with the LHCb detector at center-
of-mass energies of 7 TeV and 8 TeV. Evidence for CP violation in Bs 0 → K + K − is found for the
first time with a significance of 4.0 standard deviations.
