A semi-numerical method for one-scale problems applied to the $\overline{\rm MS}$-on-shell relation (2110.03699v1)
Published 7 Oct 2021 in hep-ph
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 $\overline{\rm MS}$ and on-shell scheme in the presence of a second heavy quark.
