Higgs production in gluon fusion beyond NNLO — •Marco Bonvini — DESY, Hamburg

I will present the construction of an approximate NNNLO expression for the Higgs production in gluon fusion with finite top mass. The approximation is based on a combination of the large- and small-x behaviours, which are known from Sudakov and BFKL resummations, respectively. We find a correction of order 15% with respect to the known NNLO result at central scales, and a significant reduction of the renormalization scale uncertainty.
