Comprehensive analysis of e+e-→γηc(2S)

  • We discuss the production of ηc(2S) through the process e+e-→γηc(2S), where the leading contribution originates from 1-loop electroweak corrections. Adopting some reasonable light-cone distribution amplitudes, we analyze the cross section of this process. As the electron-positron center of mass energy √s=3770 MeV, the typical production cross section of this process is about 1 fb.

Comprehensive analysis of e+e-→γηc(2S)

    Corresponding author: GAO Tie-Jun,

Abstract: We discuss the production of ηc(2S) through the process e+e-→γηc(2S), where the leading contribution originates from 1-loop electroweak corrections. Adopting some reasonable light-cone distribution amplitudes, we analyze the cross section of this process. As the electron-positron center of mass energy √s=3770 MeV, the typical production cross section of this process is about 1 fb.
