Abstract
We present the two first terms in the threshold expansion of Higgs production partonic crosssections at hadron colliders for processes with three partons in the final state These are contributions to the inclusive Higgs crosssection in gluon fusion at N3LO We have developed a new technique for the expansion of the squared matrixelements around the soft limit and for the reduction of the required phasespace integrals to only ten singlescale master integrals We compute the master integrals building upon modern techniques for the integration of multidimensional integrals in dimensional regularization Our results constitute an important step towards a systematic computation of the Higgs boson crosssection as an expansion around the threshold limit
