Precise Measurement of Born Cross Sections for $e^{+}{e}^{-}\to D\bar{D}$ at $\sqrt{s}=3.80-4.95$ GeV

Abstract

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. Many clear peaks in the line shape of $e^{+}{e}^{-}\to D^0{\bar{D}}^0$ and $D^{+}{D}^{-}$ around the mass range of $G(3900)$, $\psi (4040)$, $\psi (4160)$, $Y(4260)$, and $\psi (4415)$, etc., are foreseen. These results offer crucial experimental insights into the nature of hadron production in the open-charm region.
