A semi-numerical method for one-scale problems applied to the -on-shell relation
arXiv:2110.03699
Abstract
We discuss a practical approach to compute master integrals entering physical quantities which depend on one parameter. As an example we consider four-loop QCD corrections to the relation between a heavy quark mass defined in the and on-shell scheme in the presence of a second heavy quark.
