CP violation in B --> phi KS decay at large tan(beta)
Abstract
We consider the chargino contribution to the CP violation in B φ KS decay in the minimal supersymmetric standard model at large β. It is shown that the Wilson coefficient C8g of the chromomagnetic penguin operator can be significantly enhanced by the chargino-mediated diagrams while satisfying other direct/indirect experimental constraints. The enhanced C8g allows large deviation in the CP asymmetry from the standard model prediction.
