Abstract

We report a study of the decays B→Ds1(2536) +D̄(*), where D ̄(*) is D̄0, D- or D*-, using a sample of 657×106BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The branching fractions of the decays B+→Ds1(2536)+D ̄0, B0→Ds1(2536)+D- and B0→Ds1(2536)+D*- multiplied by that of Ds1(2536)+→(D *0K++D*+K0) are found to be (3.97±0.85±0.56)×10-4, (2.75±0. 62±0.36)×10-4 and (5.01±1.21±0.70) ×10-4, respectively. The ratio B(Ds1→D *0K+)/B(Ds1→D* +K0) is measured to be 0.88±0.24±0.08.
