Abstract
We study the consequences of the large dimuon asymmetry observed at D0. Physics beyond the standard model (SM) in Bs−B̄s mixing is required to explain the data. We first present a detailed analysis for model independent constraints on physics beyond the SM, and then study the implications for theoretical models which modify the SM results in different ways, such as Z′ with FCNC and R-parity violating SUSY contributions.

In contrast to the paper [ref] , it is clearly that from the upper right plot in FIG [ref], there is no region allowed by all experimental constraints within the 1 $σ$ [We notice that in [ref] , they use SM prediction directly from [ref] which use the old decay constants and bag parameters.
