Two-loop QCD corrections to the V → q q ¯ g $$ q\overline{q}g $$ helicity amplitudes with axial-vector couplings

Abstract We compute the two-loop corrections to the helicity amplitudes for the coupling of a massive vector boson to a massless quark-antiquark pair and a gluon, accounting for vector and axial-vector couplings of the vector boson and distinguishing isospin non-singlet and singlet contributions.
