Abstract
I compute the contributions of the one-loop single-real-emission amplitudes, , , etc., to inclusive Higgs boson production through next-to-next-to-next-to-leading order () in the strong coupling . The next-to-leading and next-to-next-to-leading order terms are computed in closed form, in terms of functions and the hypergeometric functions and . I compute the terms as Laurent expansions in the dimensional regularization parameter through order . To obtain the terms, I perform an extended threshold expansion of the phase space integrals and map the resulting coefficients onto a basis of harmonic polylogarithms.
