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

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.

We present a measurement of Rk+ , the branching fraction ratio B(B → K+μ+μ)=B(B → K*e+e),, for both charged and neutral B mesons. The ratio for the charged case R K* + is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q2. The analysis is based on a data sample of 711 fb−1, containing 772 × 106 BB̅ events, recorded at the ϒ(4S) resonance …
