Studies of the tracking and identification efficiencies of electrons and positrons at BESIII

Abstract

The efficiencies for electron and positron tracking and identification in the BESIII experiment are investigated with the radiative Bhabha process $e^{+}{e}^{-}\to e^{+}{e}^{-}\gamma$ from the data samples collected at the center-of-mass energies of 3.08 GeV and 3.097 GeV. The relative differences between data and MC associated with tracking and identification efficiencies of electrons and positrons, as well as the corresponding correction factors are determined. It turns out the relative differences of tracking efficiency and particle identification efficiency after correction are mostly less than 0.5$\%$ for transverse momenta $p_T>0.4$ GeV and for the entire momentum region, respectively.
