SecDec: a toolbox for the numerical evaluation of multi-scale integrals

Abstract

We present a new version of $\text{SecDec}$, a program for the numerical computation of parametric integrals in the context of dimensional regularization. By its modular structure, the $\text{python}$ rewrite $\text{pySecDec}$ is much more customizable than earlier versions of $\text{SecDec}$. The numerical integration is accelerated using code optimization available in $\text{FORM}$. With the new $\text{C++}$ interface, $\text{pySecDec}$ can provide numerical solutions of analytically unknown integrals in user-defined code.
