Direct numerical integration for multi-loop integrals
Sebastian Becker, Stefan Weinzierl
We present a method to construct a suitable contour deformation in loop momentum space for multi-loop integrals. This contour deformation can be used to perform the integration for…
Direct contour deformation with arbitrary masses in the loop
Sebastian Becker, Stefan Weinzierl
We present a method, which constructs a suitable deformation vector in loop momentum space, when the loop integration is done numerically with the help of the subtraction method. T…
Numerical evaluation of NLO multiparton processes
S. Becker, D. Goetz, C. Reuschle +2
We discuss an algorithm for the numerical evaluation of NLO multiparton processes. We focus hereby on the virtual part of the NLO calculation, i.e. on evaluating the one-loop integ…
Efficiency improvements for the numerical computation of NLO corrections
Sebastian Becker, Christian Reuschle, Stefan Weinzierl
In this paper we discuss techniques, which lead to a significant improvement of the efficiency of the Monte Carlo integration, when one-loop QCD amplitudes are calculated numerical…
