Analytic forms for the $e^{+}{e}^{-}$ annihilation cross sections around a resonance including initial state radiation

Baoxin Liu, Zhenyu Zhang, Xiang Zhou

The exact analytic form of cross sections including initial state radiation with Kuraev-Fadin radiative function are obtained for $e^{+}{e}^{-}$ annihilation around a resonance. Despite…
