Abstract

Metode redukcije tenzorskih integrala vrlo su važne za račune amplituda koje sadrže integrale po petljama. U ovom radu izložene su tri takve metode: dvije egzaktne i jedna aproksimativna. Budući da se tenzorski integrali u konačnici reduciraju na skalarne, izvedeni su i svi potrebni analitički izrazi za skalarne integrale. Konačno, sve tri metode primjenjene su na račun amplituda radijativnih procesa s narušenjem leptonskog okusa u okviru općenitog modela koji dozvoljava takav scenarij.

Abstract (english)

Reduction methods for tensor integrals are very important in calculations of amplitudes containing loop integrals. In this work, three such methods are presented: two exact and one approximate. Since tensor integrals reduce to scalar ones, all relevant scalar one-loop integrals are evaluated. Finally, amplitudes of radiative lepton flavor violating processes are calculated using all three methods in a generic model.
