Study of B -> DsJ(*)+ Dbar(*) Decays

Abstract

We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+ -> DsJ(*)+ Dbar(*)0 and B0 -> DsJ(*)+ D(*)- with the subsequent decays DsJ*(2317)+ -> Ds+ pi0, DsJ(2460)+ -> Ds+ gamma, and DsJ(2460)+ -> Ds*+ pi0. Based on a data sample of 122.1 million BBbar pairs collected with the BaBar detector at the PEP-II B factory, we obtain branching fractions for these modes, including the previously unseen decays B -> DsJ(*)+ D*. In addition, we perform an angular analysis of DsJ(2460)+ -> Ds+ gamma decays to test the different DsJ(2460)+ spin hypotheses.
