Abstract

The High Energy Jets (HEJ) framework accounts for large logarithms arising from the wide angle hard gluon emissions. The resummation in HEJ is based on an approximation to allow fast evaluation for arbitrary multiplicity. The approximation is motivated by the high energy limit and as such captures the leading logarithmic corrections in large invariant mass between the partons. These corrections are important when there is a large separation in rapidity between the produced jets. This situation arises in a Higgs boson plus jets analysis. Furthermore, HEJ includes matching to full tree level accuracy up to four jets. This talk will introduce the HEJ framework and discuss advances in the formal accuracy attained within HEJ, and the application to predictions for the production of Higgs boson plus jets.
