We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+→DsJ(*)+D̅ (*)0 and B0→DsJ(*)+D(*)- with the subsequent decays DsJ*(2317)+→Ds+π0, DsJ(2460)+→Ds+γ, and DsJ(2460)+→Ds*+π0. Based on a data sample of 122.1×106 BB̅ 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+γ decays to test the different DsJ(2460)+ spin hypotheses.

Abstract
We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+→DsJ(*)+D̅ (*)0 and B0→DsJ(*)+D(*)- with the subsequent decays DsJ*(2317)+→Ds+π0, DsJ(2460)+→Ds+γ, and DsJ(2460)+→Ds*+π0. Based on a data sample of 122.1×106 BB̅ 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+γ decays to test the different DsJ(2460)+ spin hypotheses.File in questo prodotto:
