CP asymmetries in dileptonic decays of B-meson in MSSM

Abstract

Scalar interactions (in effective Hamiltonian) can give significant variation of various experimental observables, as comparted to their respective Standard Model values, in dileptonic decays of B-meson. Also the quark level transition $b\to d{\ell }^{-}{\ell }^{+}$ can be useful to test CP violation. Here we will do comparative study of CP violation in two independent processes, which have the same quark level transition ($b\to d{\ell }^{-}{\ell }^{+}$), $B\to X_d{\ell }^{-}{\ell }^{+}$ (the inclusive decay mode) and the exclusive channel $B_d\to {\ell }^{-}{\ell }^{+}\gamma$ (radiative dileptonic decay mode). We will mainly focus on the comparative study of scalar interactions on the CP asymmetries in these two different channels.
