Measurement of branching fractions and CP asymmetries for D-s(+) -> K+ (eta, pi(0)) and D-s(+) -> pi(+) (eta,pi(0)) decays at Belle

Abstract

We report measurements of the branching fractions and CP asymmetries for D-s(+) -> K+eta, D-s(+) -> K+ pi(0), and D-s(+) -> pi(+)eta decays, and the branching fraction for D-s(+) -> 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.
