We report a study of D-sJ(*)(2317)(+) and D-sJ(2460)(+) meson production in B decays. We observe the decays B+--> D-sJ((*)+)(D) over bar ((*)0) and B-0 --> DsJ(*)+D(*)- with the subsequent decays D-sJ(*)(2317)(+)-->D(s)(+)pi(0), D-sJ(2460)(+)-->D(s)(+)gamma, and D-sJ(2460)(+)-->D(s)(*+)pi(0). Based on a data sample of 122.1x10(6) B(B) over bar 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*).

Abstract

We report a study of D-sJ(*)(2317)(+) and D-sJ(2460)(+) meson production in B decays. We observe the decays B+--> D-sJ((*)+)(D) over bar ((*)0) and B-0 --> DsJ(*)+D(*)- with the subsequent decays D-sJ(*)(2317)(+)-->D(s)(+)pi(0), D-sJ(2460)(+)-->D(s)(+)gamma, and D-sJ(2460)(+)-->D(s)(*+)pi(0). Based on a data sample of 122.1x10(6) B(B) over bar 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 D-sJ(2460)(+)-->D(s)(+)gamma decays to test the different D-sJ(2460)(+) spin hypotheses.
