Two-loop helicity amplitudes for $gg\to ZZ$ with full top-quark mass effects
We calculate the two-loop QCD corrections to gg → ZZ involving a closed top-quark loop. We present a new method to systematically construct linear combinations of Feynman integrals with a convergent parametric representation, where we also allow for irreducible numerators, higher powers of propagato...
