QCD-electroweak effects and a new prediction for Higgs production in gluon fusion process

Abstract

We discuss the recent derivation of the three-loop $\mathcal{O}(\alpha {\alpha }_s)$ 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.
