The study of D* sJ(2317)+ and D sJ(2460)+ meson production in B decays was reported. The decays B+→D(* sJ +̄D(*)0 and B0→D (*) sJ + D(*̄ was observed. The branching functions for these modes was obtained based on the sample of 122.1 × 106 B̄B pairs collected with the BABAR detector at the PEP-II B factory. An angular analysis of DsJ(2460) + → D+ s γ decays was also performed.
