Effect of supersymmetric right-handed flavor mixing onBsdecays

Abstract

Motivated by the possibility of S φK S < 0, we study the implications for Bs meson system. In a specific model that realizes S φK S < 0 with large s-b mixing, right-handed dynamics and a new CP phase, we present predictions for CP asymmetries in Bs → J/ψφ, K + K − and φγ decays. Even if the measurement of time-dependent CP asymmetry becomes hampered by very fast Bs oscillation, a finite difference between the decay rates of Bs mass eigenstates may enable the studies of CP violations with untagged data samples. Thus, studies of CP violation in the Bs system would remain useful for the extraction of new physics information.
