標題: | Measurement of branching fractions and CP asymmetries for Ds+ →k+ (η,π0) and Ds+ →π+ (η,π0) decays at Belle | 作者: | Guan Y WEI-SHU HOU et al. |
公開日期: | 2021 | 卷: | 103 | 期: | 11 | 來源出版物: | Physical Review D | 摘要: | 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. ? 2021 authors. |
