Abstract

We consider the extension of the transverse-momentum (qT) subtraction method at next-to-next-to-next-to-leading order (N3LO) in perturbative QCD. While all the qT-subtraction ingredients at qT ≠ 0 are known in analytical form, the third-order collinear functions and helicity-flip functions, which contribute only at qT=0, are approximated using a prescription which uses the known result for the total Higgs boson cross section at this order. As a first application of the third-order qT-subtraction method, we present the N3LO rapidity distribution of the Higgs boson at the LHC.
