Gehrmann, Thomas; Tancredi, Lorenzo; Weihs, Erich (2013). Two-loop QCD helicity amplitudes for gg → Z g and gg →Zγ. Journal of High Energy Physics, 2013(4):1-26.
We compute the helicity amplitudes for the processes gg → Zg and gg → Zγ to two loops in massless QCD. The perturbative expansion of these processes starts only at the one-loop level, such that our results are a crucial ingredient to the NLO corrections to Zγ and Z+jet production through gluon fusion.
