We report measurements of the branching fractions and CP asymmetries for D+ s → Kþη, Dþ s → K+π0, and D+ s → πþη decays, and the branching fraction for Dþ s → 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.
