Measurement of branching fractions and $CP$ asymmetries for $D_s^{+} \rightarrow K^+ (��, ��^0) $ and $D_s^{+} \rightarrow ��^+ (��, ��^0)$ decays at Belle

We report measurements of the branching fractions and $CP$ asymmetries for $D_s^{+} \rightarrow K^{+} ��$, $D_s^{+} \rightarrow K^{+} ��^0 $, and $D_s^{+} \rightarrow ��^{+} ��$ decays, and the branching fraction for $D_s^{+} \rightarrow ��^{+} ��^0$. Our results are based on a data sample corresponding to an integrated luminosity of 921 fb$^{-1}$ collected by the Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. Our measurements of $CP$ asymmetries in these decays are the most precise to-date; no evidence for $CP$ violation is found.
