Numerical multi-loop calculations with the program SecDec


Borowka, Sophia; Heinrich, Gudrun (2015). Numerical multi-loop calculations with the program SecDec. Journal of Physics : Conference Series, 608:012062.

Abstract

SecDec is a program which can be used for the evaluation of parametric integrals, in particular multi-loop integrals. For a given set of propagators defining the graph, the program constructs the graph polynomials, factorizes the endpoint singularities, and finally produces a Laurent series in the dimensional regularization parameter, whose coefficients are evaluated numerically. In this talk we discuss various features of the program, which extend the range of applicability. We also present a recent phenomenological example of an application entering the momentum dependent two-loop corrections to neutral Higgs boson masses in the MSSM.
