Abstract: In this talk, I will talk about a complete set of leading colour analytic helicity amplitudes for top quark pair production via gluon fusion at two-loops in QCD. These are computed including corrections due to massive fermion loops which give rise to integrals over elliptic curves. I will discuss in detail the analytic form for the finite remainders and how to obtain them using finite field sampling. Towards the end, I will also talk about an important contribution for NNLO corrections for tt-jet production.
