Seminar topic: “Polarization effects in the processes of e⁺e^– annihilation at high energy”

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. 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 fulfill the task, an analytical procedure for calculating the bremsstrahlung amplitude based on the spinor formalism was developed.
