New multiloop capabilities of FeynCalc 10

High Energy Physics - Phenomenology 2024-07-02 v1

Abstract

We briefly introduce new multiloop capabilities of the Mathematica package FeynCalc 10 and a collection of interfaces connecting FeynCalc to such popular tools as QGRAF, Fiesta, pySecDec, LoopTools, KIRA, FIRE or Fermat. In addition to that, we showcase the application of these codes to the ongoing study of the soft-overlap contribution to BcηcB_c \to \eta_c transition form factors at large hadronic recoil.
