Updated Higgs production cross section prediction

Inclusion of three-loop electroweak-QCD effects

Use of latest MSTW PDFs

Abstract

We discuss the recent derivation of the three-loop ${\cal O}(\alpha\alpha_s)$ contribution to the Higgs boson production cross section via gluon fusion arising from diagrams with light quarks, using an effective theory approach. We show results for the updated prediction of this process accounting for all the new theoretical calculations and the newest MSTW PDFs.
