(BESIII Collaboration). Observation of a Near-Threshold Structure in the K+ Recoil-Mass Spectra in e+e−→K+(DS−D0∗ + DS∗−D0)

We report a study of the processes of e^{+}e^{-}→K^{+}D_{s}^{-}D^{*0} and K^{+}D_{s}^{*-}D^{0} 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...
