A semi-numerical method for one-scale problems applied to the -on-shell relation
Matteo Fael, Fabian Lange, Kay Schönwald +1
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 r…

Exact results for and with two mass scales and up to three loops
Matteo Fael, Kay Schönwald, Matthias Steinhauser
We consider the on-shell mass and wave function renormalization constants and up to three-loop order allowing for a second non-zero quark mass. We obt…
