Recent measurements involving the newly discovered D_sJ particles are
reported. The results of D_sJ production and decay branching fraction
measurements are shown. Possible spin-parity and quark content assignments of
D_sJ mesons are discussed. The results are based on a large data sample
recorded by the Belle detector at the KEKB e^+ e^- collider.Comment: 4 pages, 3 figures, proceedings to the talk given on behalf of the
