Description
LHC data is forcing the theory community to push their calculations to an unprecedented level of precision in multiple phase-space regions. In the High-Energy region, the perturbative convergence of the hard scattering cross-sections can be impeded by large logarithms in $s/t$ which can be numerically significant at LHC energies. These logarithms are especially important in key regions of phase-space, e.g. in the VBF region in Higgs boson analyses.
The High-Energy Jets (HEJ) framework is a perturbative framework which resums these logarithms to Leading Logarithmic accuracy in $s/t$ for a large range of processes. In this talk, I will show how these logarithms appear, how they can be resummed in HEJ and present some of the studies which make their phenomenological relevance manifest, including recent new results for Higgs-plus-one-jet analyses (arXiv:2210.10671).
