Description
I will discuss the computation of the Higgs rapidity distribution at N3LO in the gluon fusion production mode. Our approach relies on the fully analytic computation of six terms in a systematic expansion of the partonic differential cross section around the production threshold of the Higgs boson at next-to-next-to-next-to leading order in QCD perturbation theory.  We observe a mild correction compared to previous perturbative order and a significant reduction of the dependence of the cross section on the perturbative scale throughout the entire rapidity range.
