Search for the D ∗ sJ (2632)+ at BaBar The BABAR Collaboration

We have performed a search for theD sJ(2632) + state recently reported by the SELEXCollaboration at FNAL. This preliminary analysis makes use of an integrated luminosity of 125 fb collected by the BABAR detector at the PEP-II asymmetric-energy ee collider. The resulting D s η and DK mass spectra show no evidence for the D sJ(2632) + state. In addition, no signal is observed in the DKS mass spectrum.
