Massive vector form factors to three loops
Matteo Fael, Fabian Lange, Kay Schoenwald +1
We compute the three-loop non-singlet corrections to the photon-quark form factors taking into account the full dependence on the virtuality of the photon and the quark mass. We co…
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…
A semi-analytic method to compute Feynman integrals applied to four-loop corrections to the -pole quark mass relation
Matteo Fael, Fabian Lange, Kay Schönwald +1
We describe a method to numerically compute multi-loop integrals, depending on one dimensionless parameter and the dimension , in the whole kinematic range of . The metho…
Reconstructing Rational Functions with
Jonas Klappert, Fabian Lange
We present the open-source library for the reconstruction of multivariate rational functions over finite fields. We discuss the involved algorithm…
