Exact two-loop amplitudes for Higgs plus jet production with a cubic Higgs self-coupling

Abstract We compute the corrections to the two-loop amplitudes for gg → h, gg → hg, qg → hq, and q q ¯ $$ q\overline{q} $$ → hg due to a modified cubic Higgs self-coupling. The exact dependence on the Higgs and top-quark masses across the entire 2 → 2 phase space is determined by numerically solving...
