Seminar topic: “Radiative corrections for lepton collider experiments with polarized beams” (based on PhD thesis)

Speaker: Vitaly Yermolchyk (DLNP JINR)

Abstract:

Experiments with polarized high-energy electron-positron beams are being actively developed. In addition, projects with one or two polarized muon beams have been proposed. The paper presents the calculation of electroweak corrections for the muon-electron scattering and Moeller process (including the muon-muon scattering variant). Taking into account the planned accuracy of the experiments the mass of leptons is kept in the calculations. The results can be useful in experiments at low energies. In the example of the e⁺e^– → HZ process, higher order electroweak corrections were taken into account. The results of theoretical calculations are implemented in the form of the ReneSANCe Monte Carlo generator.
