Radiative Corrections and Polarization Effects to Møller Scattering

Polarization effects including radiative corrections have been considered. Exact lowest-order covariant calculation of QED RC has been carried out and detailed numerical analysis is given. The hard photon contribution is calculated analytically. Exponentation procedure is used to consider multi-soft-photon contribution. Numerical analysis is perfomed for beam polarization measurements at Møller polarimeter.

The Impact

We calculate full \(\mathcal{O}(\alpha)\) electroweak radiative corrections and \(\mathcal{O}(\alpha^3)\) initial state radiation (ISR) corrections to \(e^-e^+ \rightarrow W^-W^+\) with initial beam polarization effects. In phenomenological results, we study the impact of electroweak and ISR corrections on cross-sections as well as their relevant distributions. We find that the corrections are order of 10% contributions. They are sizable contributions and should be taken into account at future lepton colliders.

Bremsstrahlung Contribution

The problem of the bremsstrahlung contribution calculation as a part of the radiative corrections in the case of single gauge boson production was discussed. It was shown that the hard photon bremsstrahlung contribution can be divided into the finite and divergent terms. The exact calculation of soft photon bremsstrahlung and infrared part of hard photon bremsstrahlung was presented in frame of the dimensional regularization scheme. Numerical analysis of radiative corrections to the cross sections of single gauge boson production was performed.
