We summarise the calculation of the two-loop next-to-leading order QCD corrections to Z boson plus Higgs boson production in gluon fusion. The result presented includes full top-quark mass effects and is obtained by combining two-loop virtual contributions computed numerically, using sector decomposition, with virtual contributions obtained in a high-energy expansion. We find that the corrections enhance the cross-section by approximately a factor of 2 and reduce the renormalisation and factorisation scale uncertainty by around 30%. For a centre of mass energy of √ 𝑠 = 13 . 6 TeV we obtain We also observe that the choice of top-quark mass renormalisation scheme can have a significant impact on the prediction.
