Two-Loop Matching onto Dimension Eight Operators in the Higgs-Glue Sector

Abstract

This letter presents results for the two-loop matching coefficients for the dimension eight operators that contribute to Higgs production via gluon fusion. The coefficients can be used to calculate the first correction to the infinite top mass limit to Higgs production with large transverse momentum at two loops. To date such processes have been studied at two loop order only in the leading term in the top mass expansion. These corrections become enhanced in processes with large final state invariant mass, typical of multijet processes.
