Numerical evaluation of two-loop integrals with pySecDec
S. Borowka, G. Heinrich, S. Jahn +3
We describe the program pySecDec, which factorises endpoint singularities from multi-dimensional parameter integrals and can serve to calculate integrals occurring in higher order…
NLO and off-shell effects in top quark mass determinations
G. Heinrich, A. Maier, R. Nisius +4
We study the impact of different theoretical descriptions of top quark pair production on top quark mass measurements in the di-lepton channel. To this aim, the full NLO correction…
Multi-loop calculations: numerical methods and applications
S. Borowka, G. Heinrich, S. Jahn +3
We briefly review numerical methods for calculations beyond one loop and then describe new developments within the method of sector decomposition in more detail. We also discuss ap…
pySecDec: a toolbox for the numerical evaluation of multi-scale integrals
S. Borowka, G. Heinrich, S. Jahn +4
We present pySecDec, a new version of the program SecDec, which performs the factorisation of dimensionally regulated poles in parametric integrals, and the subsequent numerical ev…
