CP violation in the $B\to K{\ell }^{+}{\ell }^{-}$ decay

Abstract

Standard Model (SM) CP asymmetries in $B\to K{\ell }^{+}{\ell }^{-}$ are expected to be very small. This feature could help in the understanding of new physics scenarios which predict the existence of CP odd phases in various Wilson coefficients. In this paper we have analyzed the $B\to K{\ell }^{+}{\ell }^{-}$ decay in beyond the SM scenarios where the Wilson coefficients have new CP odd phases. The sensitivity of the CP asymmetries on these new weak phases is discussed.
