We discuss the production of ηc (2S) through the process e+e- -→γηc (2S), where the leading contributionoriginates from l-loop electroweak corrections. Adopting some reasonable light-cone distribution amplitu...

Applying an effective Lagrangian method and an on-shell scheme, we analyze the electroweak corrections to the rare decay b→, s+γ from some special two loop diagrams in which a closed heavy fermion loop is attached ...

We analyze the cross section of e + e-→τ + μ-within the frameworks of SM and its Z extension.The theoretical prediction of the SM on the total cross section is suppressed by the tiny neutrino masses.On the other ha...
