Sophia Borowka, Jonathon Carter, Gudrun Heinrich
TL;DR
SecDec 2.0 is a software tool that automates the extraction of divergences and numerical evaluation of multi-loop integrals and phase space integrals without kinematic restrictions.
Contribution
This paper introduces SecDec 2.0, a new version of the program that enhances automated pole extraction and numerical evaluation for complex multi-loop calculations.
Findings
Automated pole extraction from multi-loop integrals.
Numerical evaluation of finite functions without kinematic restrictions.
Applicable to phase space integrals in addition to loop integrals.
Abstract
The version 2.0 of the program SecDec is described, which can be used for the extraction of poles within dimensional regularisation from multi-loop integrals as well as phase space integrals. The numerical evaluation of the resulting finite functions is also done by the program in an automated way, with no restriction on the kinematics in the case of loop integrals.
