Measurement of and branching fractions
Abstract
We report a measurement of the B0 and B+ meson decays to the D$$^{–}_{s}$$K$$^{0}_{S}$$π+ and D$$^{–}_{s}$$K+K+ final states, respectively, using 657 × 106BB¯ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e– collider. Using the D$$^{–}_{s}$$ → Φπ–, K* (892)0K– and K$$^{0}_{S}$$K– decay modes for the Ds reconstruction, we measure the following branching fractions: B(B0 → $$^{–}_{s}$$K$$^{0}_{S}$$π+) = [0.47± 0.06(stat) ± 0.05(syst)] × 10–4 and B(B+ → $$^{–}_{s}$$K+K+) = [0.93 ± 0.22(stat) ± 0.10(syst)] × 10–5. We find the ratio of the branching fraction of B+ → $$^{–}_{s}$$K+K+ to that of the analogous Cabibbo-favored B+ →$$^{–}_{s}$$K+π+ decay to be RB = 0.054 ± 0.013(stat) ± 0.006(syst), which is consistent with the naive factorization model. We also observe a deviation of the DsK invariant-mass distribution from the three-body phase-space model for both studied decays.
