Abstract

The DsJ(2317) and DsJ in B decays was observed. The observation of DsJ(2457)→Dsγ decay eliminated the zero spin of DsJ(2457). The angular analysis of this decay supported the hypothesis that the DsJ(2457) is a 1+ state. The possible feed across between all studied DsJ decay modes using Monte Carlo methods was analyzed. For each mode, branching fractions that are consistent with the world average values were measured.
