Measurement of CP asymmetries and branching-fraction ratios for B±→DK± and Dπ± with D→K0SK±π∓ using Belle and Belle II data

The Belle II collaboration (I. Adachi, ..., N. Anh Ky, ...)

We measure CP asymmetries and branching-fraction ratios for B± → DK± and Dπ± decays with D → K0 SK±π∓, where D is a superposition of D0 and ¯D 0. We use the full data set of the Belle experiment, containing 772 × 106 B¯B pairs, and data from the Belle II experiment, containing 387×106 B¯B pairs, both collected in electron-positron collisions at the Υ(4S) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ3.
