Abstract

We measure CP asymmetries and branching-fraction ratios for B^± → DK^± and Dπ^± decays with D → KS0 K^± π^∓, where D is a superposition of D⁰ and D¯⁰. We use the full data set of the Belle experiment, containing 772 × 10⁶ BB¯ pairs, and data from the Belle II experiment, containing 387 × 10⁶ BB¯ pairs, both collected in electron-positron collisions at the Υ(4S) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ ₃. [Figure not available: see fulltext.]
