Measurement of branching fractions and asymmetries for and decays at Belle
Abstract
We report measurements of the branching fractions and CP asymmetries for $$D_s^{+} \rightarrow K^{+} \eta$$, $$D_s^{+} \rightarrow K^{+} \pi^0$$ , and $$D_s^{+} \rightarrow \pi^{+} \eta$$ decays, and the branching fraction for $$D_s^{+} \rightarrow \pi^{+} \pi^0$$. 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.
