Abstract

We report a study of the decays $B \to D_{s 1} (2536)^{+} {\bar{D}}^{(*)}$ , where ${\bar{D}}^{(*)}$ is ${\bar{D}}^{0}$ , $D^{-}$ or $D^{* -}$ , using a sample of $657 \times 10^{6} B \bar{B}$ pairs collected at the $Υ (4 S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider. The branching fractions of the decays $B^{+} \to D_{s 1} (2536)^{+} {\bar{D}}^{0}$ , $B^{0} \to D_{s 1} (2536)^{+} D^{-}$ and $B^{0} \to D_{s 1} (2536)^{+} D^{* -}$ multiplied by that of $D_{s 1} (2536)^{+} \to (D^{* 0} K^{+} + D^{* +} K^{0})$ are found to be $(3.97 \pm 0.85 \pm 0.56) \times 10^{- 4}$ , $(2.75 \pm 0.62 \pm 0.36) \times 10^{- 4}$ and $(5.01 \pm 1.21 \pm 0.70) \times 10^{- 4}$ , respectively. The ratio $B (D_{s 1} \to D^{* 0} K^{+}) / B (D_{s 1} \to D^{* +} K^{0})$ is measured to be $0.88 \pm 0.24 \pm 0.08$ .
