Measurement of $CP$ asymmetries and branching-fraction ratios for $B^{\pm} \to D K^{\pm}$ and $D\pi^{\pm}$ with $D \to K_S^0 K^{\pm} \pi^{\mp}$ using Belle and Belle II data
Abstract
We measure CP asymmetries and branching-fraction ratios for B± → DK± and Dπ±
decays with D → K0
S K±π∓, where D is a superposition of D0 and D0. 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 φ3.
