Model independent analysis of a class of ${\bar{B}}_s^0$ decay modes

Abstract

The widths of a class of two-body ${\bar{B}}_s^0$ decays induced by $b\to c\bar{u}d$ and $b\to c\bar{u}s$ transitions are determined in a model-independent way, using $SU(3{)}_F$ symmetry and existing information on $\bar{B}\to D_{(s)}P$ and $\bar{B}\to D_{(s)}V$ decays, with $P$ and $V$ a light pseudoscalar or vector meson. The results are relevant for the $B_s$ physics programmes at the hadron colliders and at the $e^{+}{e}^{-}$ factories running at the peak of ${\rm Y}(5S)$.
