Venue: online seminar on Zoom, Bogoliubov Laboratory of Theoretical Physics
Seminar topic: «Evaluation of Bremsstrahlung helicity amplitudes with Dirac spinor algebra»
Speaker: Yahor Dydyshka (DLNP JINR)
Abstract:
Helicity amplitudes in QED with massive fermions can be written in tensor form using Dirac spinors (bi-spinors). The approach is demonstrated on the examples of hard Bremsstrahlung in processes e+e– → Z, ZZ, Z γ.
