Description

The processes of electron-positron annihilation into a virtual photon or a Z-boson is considered. QED radiative corrections due to the initial state radiation in these processes are estimated upto the $\mathcal{O} (\alpha^5)$ order within the leading and next-to-leading logarithmic approximations. The results are relevant for verification of the Standard Model and searches for new physical phenomena at future high-luminosity electron-positron colliders such as the FCC-ee (CERN) and CEPC (China).
