The D0 Collaboration reported a 3.2σ deviation from the standard model (SM) prediction in the like-sign dimuon asymmetry. Assuming that new physics contributes only to B(d,s) mixing, we show that the data can be analyzed without using the theoretical calculation of ΔΓ(s), allowing for robust interpretations. We find that this …
