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.
