摘要：

We consider the chargino contribution to CP violation in B-->phiK(S) decay in the minimal supersymmetric standard model at large tan beta. It is shown that the Wilson coefficient C-8g of the chromomagnetic penguin operator can be significantly enhanced by the chargino-mediated diagrams while satisfying other direct or indirect experimental constraints. The enhanced C-8g allows a large deviation in the CP asymmetry from the standard model prediction, especially it can explain the apparent anomaly reported by BaBar and Belle.
