Measurements of the center-of-mass energies of e+e-collisions at BESIII

Ablikim, Medina N.; Achasov, M. N.; Adlarson, Patrik; Ahmed, Shakeel; Albrecht, Malte; Kolcu, Onur Bugra (IOP Publishing, 2021)

During the 2016-17 and 2018-19 running periods, the BESIII experiment collected 7.5 fb -1 of e+e- collision data at center-of-mass energies ranging from 4.13 to 4.44 GeV. These data samples are primarily used for the study ...
