Abstract

We report measurements of the branching fractions and CP asymmetries for Ds+→K+η, Ds+→K+π0, and Ds+→π+η decays, and the branching fraction for Ds+→π+π0. 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.
