Abstract

A narrow state, which we label DsJ(2458)+, with a mass 2458.0±1.0(stat)±1.0(syst)MeV/c2, is observed in the inclusive D+sπ0γ mass distribution in 91fb−1 of e+e− annihilation data recorded by the BABAR detector at the SLAC PEP-II asymmetric-energy e+e− storage ring. The observed width is consistent with the experimental resolution. The data favor decay through D*s(2112)+π0 rather than through D*sJ(2317)+γ. An analysis of D+sπ0 data 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.
