Description

At the LHC the dominant production channel for the Higgs-boson with two
jets is through gluon fusion, which is therefore also the dominant background for measuring the Higgs-boson production through weak boson fusion. To reduce the gluon fusion component WBF cuts require a large invariant mass of the dijet system. Thus the predictions become sensitive to a high energy logarithm. We present new calculations in the framework for High Energy Jets to resume such logarithms, while keeping the full quark mass dependences in the gluon to Higgs-boson coupling.
Compared to the infinite top mass approximation we found a reduction of 10% in the cross-section after WBF cuts.
