DESCRIPTION:We present the two-loop virtual corrections to gg→ZH involvi
ng a closed top-quark loop. These amplitudes provide the missing ingredien
t required to compute the NLO QCD corrections to Higgs boson production in
association with a Z-boson in gluon fusion. The two-loop integrals\, invo
lving massive top-quarks\, are first expressed in terms of finite integral
s and are then calculated numerically. We will describe the techniques use
d to obtain and evaluate these amplitudes and present comparisons to vario
us approximations in the literature. We will discuss an upcoming public re
lease of pySecDec\, the tool used to compute these corrections\, and highl
ight a new feature that simplifies the numerical computation of amplitudes
