Abstract

We report the first observation of the B\ensuremath→DD_sJ(2317) and B\ensuremath→DD_sJ(2457) decays based on 123.8\ifmmode×\else\texttimes\fi10⁶ BB events collected with the Belle detector at KEKB. We observe the D_sJ(2317) decay to D_s\ensuremathπ⁰ and the D_sJ(2457) decay to the D_s^*\ensuremathπ⁰ and D_s\ensuremathγ final states. We also set 90% C.L. upper limits for the decays D_sJ(2317)\ensuremath→D_s^*\ensuremathγ, D_sJ(2457)\ensuremath→D_s^*\ensuremathγ, D_sJ(2457)\ensuremath→D_s\ensuremathπ⁰, and D_sJ(2457)\ensuremath→D_s\ensuremathπ⁺\ensuremathπ^\ensuremath-.
