TLDR
In this article, the BESIII detector at center-of-mass energies between 3.810 GeV and 4.600 GeV was used to study the charmonium-like states and high-excited CHARM states and the time-integrated luminosity of the collected data sample was measured to a precision of 1% by analyzing events produced by the large-angle Bhabha scattering process.
Abstract
From December 2011 to May 2014, about 5 fb(-1) of data were taken with the BESIII detector at center-ofmass energies between 3.810 GeV and 4.600 GeV to study the charmonium-like states and higher excited charmonium states. The time-integrated luminosity of the collected data sample is measured to a precision of 1% by analyzing events produced by the large-angle Bhabha scattering process.
