Seminar topic: “Polarization Effects in the Processes of e+e- Annihilation at High Energies”
Speaker: Yahor Dydyshka
Abstract:
The work is devoted to the calculation of electroweak radiative corrections, taking into account the polarization of initial and final particles, for a number of processes at future electron-positron colliders. The results were obtained for electron-positron scattering, the process of annihilation into a lepton pair, the process of associated Higgs boson and Z-boson production, and the process of photon−Z-boson pair production. To fulfil the task, an analytical procedure for calculating the bremsstrahlung amplitude based on the spinor formalism was developed.
