The observed width is consistent with the experimental resolution. The data favor decay through D*s(2112)+π0rather than through D*sJ(2317)+γ. An analysis of Ds+π0data accounting for the influence of the DsJ(2458)+produces a D*sJ(2317)+mass of 2317.3±0.4 (stat)±0.8 (syst) MeV/c2. © 2004 The American Physical Society.
