Observation of a Near-Threshold Structure in the $K^+$ Recoil-Mass Spectra in $e^+e^- \rightarrow K^+(D_s^-D^{*0}+D_s^{*-}D^0$)
[arXiv:2011.07855]
We report a study of the processes of e+e-→K+Ds-D*0 and K+Ds*-D0 based on e+e- annihilation samples collected with the BESIII detector operating at BEPCII at five center-of-mass energies ranging from 4.628 to 4.698 GeV with a total integrated luminosity of 3.7 fb-1. An excess of events over the known contributions of the conventional charmed mesons is observed near the Ds-D*0 and Ds*-D0 mass thresholds in the K+ recoil-mass spectrum for events collected at s=4.681 GeV.
