Description

In this talk the new version of the public program SecDec 2.0 for the numerical evaluation of multi-loop integrals with several mass scales is presented. The program is based on sector decomposition to extract dimensionally regulated singularities. To deal with integrable singularities due to mass thresholds, the integration contour is deformed into the complex plane. As applications, numerical results for several two-loop integrals are given, including non-planar two-loop four-point functions entering heavy quark pair production at NNLO.
