摘要：
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(1/2)=3770 MeV, the typical production cross section of this process is about 1 fb.
