Title: Studies of D{sub sJ}{sup (*)} Production in B Decays and e+e- {yields} cc-bar Events

Abstract

We report a study of D{sub sJ}*(2317){sup +} and DsJ(2460)+ meson production in B decays. We observe and measure branching fractions for the decays B{sup +} {yields} D{sub sJ}{sup (*)+}D-bar{sup (*)0} and B{sup 0} {yields} D{sub sJ}{sup (*)+}D-bar{sup (*)-} with the subsequent decays D{sub sJ}*(2317){sup +} {yields} D{sub s}{sup +}{pi}{sup 0}, D{sub sJ}(2460){sup +} {yields} D{sub s}*{sup +}{pi}{sup 0}, and D{sub sJ}(2460){sup +} {yields} D{sub s}{sup +}{gamma}. In addition, we perform an angular analysis of D{sub sJ}(2460){sup +} {yields} D{sub s}{sup +}{gamma} decays to test the different DsJ(2460)+ spin hypotheses.From a dataset of e+e- {yields} cc-bar events we measure the masses of the D{sub sJ}*(2317){sup +} and DsJ(2460)+ mesons and the D{sub sJ}(2460){sup +} {yields} D{sub s}{sup +}{gamma} and D{sub sJ}(2460){sup +} {yields} D{sub s}{sup +}{pi}{sup +}{pi}{sup -} branching fractions. A search is performed for neutral and doubly-charged partners.We have also searched for the D{sub sJ}*(2632){sup +} reported by the SELEX collaboration at FNAL. The resulting D{sub s}{sup +}{eta} and D0K+ mass spectra show no evidence for the D{sub sJ}*(2632){sup +} state. In addition, no signal is observed in the D*+Ks mass spectrum.All the above studies are performed on data samples collected with the BaBar detector at the SLAC PEP-IImore » B factory.« less
