Abstract:
We measure CP asymmetries and branching-fraction ratios for B ± → DK ± and Dπ ± decays with D → $$ {K}_{\textrm{S}}^0 $$ K S 0 K ± π ∓ , where D is a superposition of D 0 and $$ \overline{D} $$ D ¯ 0 . We use the full data set of the Belle experiment, containing 772 × 10 6 $$ B\overline{B} $$ B B ¯ pairs, and data from the Belle II experiment, containing 387 × 10 6 $$ B\overline{B} $$ B B ¯ pairs, both collected in electron-positron collisions at the Υ(4 S ) resonance. Our results provide model-independent information on the unitarity triangle angle ϕ 3 .
