Description
We present a study of quark-initiated contributions to Higgs boson pair production. Our result include the NLO QCD corrections to the electroweak quark-antiquark channel and the interference between the electroweak and QCD quark-initiated amplitudes. We compute the two-loop amplitudes analytically using the method of differential equations, with boundary conditions obtained from the large-mass expansion of the canonical master integrals. The one-loop amplitudes are computed using GoSam. All results are implemented in the POWHEG-BOX framework for phenomenological studies, resulting in sizable distortions of differential distributions.
