Search for the D_(sJ)(2632)^+ at BaBar

Abstract

We have performed a search for the $D_{sJ}^{\ast }(2632{)}^{+}$ state recently reported by the SELEX Collaboration at FNAL. This preliminary analysis makes use of an integrated luminosity of 125 ${\mathrm{fb}}^{-1}$ collected by the BaBar detector at the PEP-II asymmetric-energy $e^{+}{e}^{-}$ collider. The resulting $D_s\eta$ and $D^0{K}^{+}$ mass spectra show no evidence for the $D_{sJ}^{\ast }(2632{)}^{+}$ state. In addition, no signal is observed in the $D^{\ast +}{K}_S$ mass spectrum.
