Bierenbaum, Isabella; Czakon, Michał; Mitov, Alexander The singular behavior of one-loop massive QCD amplitudes with one external soft gluon. (English) Zbl 1246.81420 Nucl. Phys., B 856, No. 2, 228-246 (2012). Summary: We calculate the one-loop correction to the soft-gluon current with massive fermions. This current is process independent and controls the singular behavior of one-loop massive QCD amplitudes in the limit when one external gluon becomes soft. The result derived in this work is the last missing process-independent ingredient needed for numerical evaluation of observables with massive fermions at hadron colliders at the next-to-next-to-leading order.
