Precise Measurement of Born Cross Sections for \(e^+e^-\to D\bar{D}\) and Observation of One Structure between \(\sqrt{s} = 3.80-4.95\) GeV

By Besiii Collaboration and others
Using data samples collected with the BESIII detector at the BEPCII collider at center-of-mass energies ranging from 3.80 to 4.95 GeV, corresponding to an integrated luminosity of 20 fb\(^{-1}\), a measurement of Born cross sections for the \(e^+e^-\to D^{0}\bar{D}^{0}\) and \(D^{+}D^{-}\) processes is presented with unprecedented precision.
