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…

Charm-quark mass effects in NRQCD matching coefficients and the leptonic decay of the meson
Manuel Egner, Matteo Fael, Jan Piclum +2
We compute two-loop corrections to the vector current matching coefficient involving two heavy quark masses. The result is applied to the computation of the decay width int…
