Lessons from the LHCb measurement of CP violation in B s → K + K −

Abstract The LHCb experiment measured the time-dependent CP asymmetries C KK and S KK in B s → K + K − decay. Combining with the corresponding CP asymmetries C ππ and S ππ in B → π + π − decay, we find that the size of U-spin breaking in this system is of order 20%. Moreover, the data suggest that t...
