Three-loop on-shell Feynman integrals with two masses. (English) Zbl 1194.81252

Nucl. Phys., B 819, No. 1-2, 183-200 (2009).
Summary: All three-loop on-shell QCD Feynman integrals with two masses can be reduced to 27 master integrals. Here we calculate these master integrals, expanded in \(\epsilon \), both exactly in the mass ratio and as series in limiting cases.
