Abstract: (arXiv)
We report on our search for , \bar{B^0} \to D_s^{(*)+} \KS \pi^-, and decays in 383 million Upsilon(4S) \to B \bar{B}B{\cal B}(B^- \to D^+_s K^- \pi^-) = (2.02 \pm 0.13_{stat} \pm 0.38_{syst}) \times 10^{-4},{\cal B}(B^- \to D^{*+}_s K^- \pi^-)= (1.67 \pm 0.16_{stat} \pm 0.35_{syst}) \times 10^{-4},{\cal B}(\bar{B^0} \to D_s^{+} \KS \pi^-)= (0.55 \pm 0.13_{stat} \pm 0.10_{syst}) \times 10^{-4},{\cal B}(B^- \to D_s^{+} K^- K^-) = (0.11 \pm 0.04_{stat} \pm 0.02_{syst}) \times 10^{-4}{\cal B}(\bar{B^0} \to D_s^{*+} \KS \pi^-)< 0.55 \times 10^{-4}{\cal B}(B^- \to D_s^{*+} K^- K^-) < 0.15 \times 10^{-4}.$Note:
