Abstract
The process e+e−→D*+sD∗s0(2317)−+c.c. is observed for the first time with the data sample of 567 pb−1 collected with the BESIII detector operating at the BEPCII collider at a center-of-mass energy √s=4.6 GeV. The statistical significance of the D∗s0(2317)± signal is 5.8σ and the mass is measured to be (2318.3±1.2±1.2) MeV/c2. The absolute branching fraction B(D∗s0(2317)±→π0D±s) is measured as 1.00+0.00−0.14(stat)+0.00−0.14(syst) for the first time. The uncertainties are statistical and systematic, respectively.
