"QED final state bremsstrahlung of light fermion pair in PHOTOS Monte Carlo"
mgr Sergii Antropov (NZ42)
Abstract:
I present results for final state emissions of additional leptonic pairs in decays of heavy intermediate state such as Z boson. An effective factorization of matrix element of 2f → Z/γ∗ → 4f spin summated process is proposed to separate Born level matrix element from the factorized part describing extra pair emission from the final state. An improvement in PHOTOS generated spectrum of invariant mass squared of muon pair is reduction of discrepancy (from factor of 4.2 to 7%) with reference spectrum for the hardest extra pair emissions.
