Measurement of B→Ds(*)+D*(*) branching fractions
Measurement of B→Ds(*)+D*(*) branching fractions
This article describes improved measurements by CLEO of the ${B}^{0}\ensuremath{\rightarrow}{D}_{s}^{+}{D}^{*\ensuremath{-}}$ and ${B}^{0}\ensuremath{\rightarrow}{D}_{s}^{*+}{D}^{*\ensuremath{-}}$ branching fractions, and first evidence for the decay ${B}^{+}\ensuremath{\rightarrow}{D}_{s}^{(*)+}{D}^{**0},$ where ${D}^{**0}$ represents the sum of the ${D}_{1}{(2420)}^{0},$ ${D}_{2}^{*}{(2460)}^{0},$ and ${D}_{1}{(j=1/2)}^{0}L=1$ charm meson states. Also reported is the first measurement of the ${D}_{s}^{*+}$ polarization in the decay ${B}^{0}\ensuremath{\rightarrow}{D}_{s}^{*+}{D}^{*\ensuremath{-}}.$ A …
