Abstract

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.
