Observation of a new D_sJ meson in B+->D0BD0K+ decays

Abstract

We report the observation of a new $D_{sJ}$ meson produced in $B^{+}\to {\bar{D}}^0{D}_{sJ}\to {\bar{D}}^0{D}^0{K}^{+}$. This state has a mass of $M=2708\pm 9_{-10}^{+11}\mathrm{MeV}/c^2$, a width $\Gamma =108\pm 23_{-31}^{+36}\mathrm{MeV}/c^2$ and a $1^{-}$ spin-parity. The results are based on an analysis of 449 million $B\bar{B}$ events collected at the ${\rm Y}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider.
