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 flavor changing neutral current and R-parity violating supersymmetry contributions. © 2010 The American Physical Society.
