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 D 0 D ¯ 0 and D + D processes is presented with unprecedented precision. Many clear peaks in the line shape of e + e D 0 D ¯ 0 and D + D around the mass range of G ( 3900 ) , ψ ( 4040 ) , ψ ( 4160 ) , Y ( 4260 ) , and ψ ( 4415 ) , etc., are foreseen. These results offer crucial experimental insights into the nature of hadron production in the open-charm region. Published by the American Physical Society 2024
