Luminosities and energies of e(+)e(-) collision data taken between root s=4.61 gev and 4.95 gev at BESIII
(IOP Publishing Ltd, 2022)
From December 2019 to June 2021, the BESIII experiment collected approximately 5.85 fb(-1) of data at center-of-mass energies between 4.61 and 4.95 GeV. This is the highest collision energy BEPCII has reached to date. The ...
Number of J/psi events at BESIII
(IOP Publishing, 2022)
Using inclusive decays of J/psi, a precise determination of the number of J/psi events collected with the BESIII detector was performed. For the two data sets taken in 2009 and 2012, the numbers of J/psi events were ...
