Effect of supersymmetric right-handed flavor mixing onBsdecays

Abstract

Motivated by the possibility of ${\mathcal{S}}_{\ensuremath{\phi}{K}_{S}}<0$, we study the implications for the ${B}_{s}$ meson system. In a specific model that realizes ${\mathcal{S}}_{\ensuremath{\phi}{K}_{S}}<0$ with large $s\mathrm{\text{\ensuremath{-}}}b$ mixing, right-handed dynamics, and a new CP phase, we present predictions for CP asymmetries in ${B}_{s}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$, ${K}^{+}{K}^{\ensuremath{-}}$, and $\ensuremath{\phi}\ensuremath{\gamma}$ decays. Even if the measurement of time-dependent CP asymmetry becomes hampered by very fast ${B}_{s}$ oscillation, a finite difference between the decay rates of ${B}_{s}$ mass eigenstates may enable the studies of CP violations with untagged data samples. Thus, studies of CP violation in the ${B}_{s}$ system would remain useful for the extraction of new physics information.
