Description
We present two-loop scattering amplitudes in QCD for the hadronic production of a Higgs boson in association with two jets mediated by the top-quark Yukawa coupling.
Our results cover the dominant contributions for all partonic channels, which are computed in the heavy top-mass limit in the leading-color approximation.
We obtained analytic expressions of the amplitudes decomposed in an integral basis by reconstructing the integral coefficients from numerical evaluations in finite fields.
To handle the amplitudes' complexity, we exploited their analytic properties, reducing the required number of samples for the reconstruction and leading to compact representations.
Finally, we studied the singularity structure of the amplitudes and find surprising non-analytic behaviour in the bulk of the physical phase space.
