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.Measurement of branching fractions and CP asymmetries for Ds+ →k+ (η,π0) and Ds+ →π+ (η,π0) decays at Bellejournal article10.1103/PhysRevD.103.1120052-s2.0-85108217690
