摘要：
The Dempty set Collaboration reported a 3.2 sigma deviation from the standard model prediction in the like-sign dimuon asymmetry. Assuming that new physics contributes only to B-d,B-S mixing, we study the general implications of the measurement, and then in the context of the general minimal flavor violation (GMFV) framework. We find that this framework gives a good fit to the data. Universal new physics with similar contributions relative to the SM in the B-d and B-s systems are possible, but the data favor a larger deviation in B-s than in B-d mixing. We also briefly discuss the GMFV contributions to CP violation in D-0 - (D) over bar (0) mixing.
