Chen, Long and Heinrich, Gudrun and Jones, Stephen P. and Kerner, Matthias and Klappert, Jonas and Schlenk, Johannes (2021) 'ZH production in gluon fusion: two-loop amplitudes with full top quark mass dependence.', Journal of high energy physics., 2021 .
We present results for the two-loop helicity amplitudes entering the NLO QCD corrections to the production of a Higgs boson in association with a Z -boson in gluon fusion. The two-loop integrals, involving massive top quarks, are calculated numerically. Results for the interference of the finite part of the two-loop amplitudes with the Born amplitude are shown as a function of the two kinematic invariants on which the amplitudes depend.
