We measure CP asymmetries and branching-fraction ratios for B±→ DK± and Dπ± decays with D →KS0K±π∓, where D is a superposition of D0 and D‾0. We use the full data set of the Belle experiment, containing 772 × 10^6 BB‾pairs, and data from the Belle II experiment, containing 387 × 10^6 BB‾ pairs, both collected in electron-positron collisions at the Υ(4S) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ3.

Abstract
We measure CP asymmetries and branching-fraction ratios for B±→ DK± and Dπ± decays with D →KS0K±π∓, where D is a superposition of D0 and D‾0. We use the full data set of the Belle experiment, containing 772 × 10^6 BB‾pairs, and data from the Belle II experiment, containing 387 × 10^6 BB‾ pairs, both collected in electron-positron collisions at the Υ(4S) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ3.File in questo prodotto:
