Logarithmic corrections for Jet Production at the LHC

Description

Several important processes and analyses at the LHC are sensitive to higher-order perturbative corrections beyond what can currently be calculated at fixed order. One important class of large logarithmic corrections are so-called high-energy logarithms which appear when the centre-of-mass energy of a QCD collision is much larger than the transverse momenta of the observed jets.
The effect of these logarithms is enhanced when there is a large rapidity separation between jets. It is therefore particularly important to study the effect of these higher-order corrections in, for example, the analysis of Higgs boson production in association with jets, as vector-boson fusion cuts provide exactly this enhanced impact to the gluon-fusion channel.
In this talk I will describe the High Energy Jets framework, which includes the dominant high-energy logarithms to provide all-order predictions for several relevant LHC processes including Higgs, W, or Z boson production in association with at least two jets. I will summarise the results from arXiv:1812.08072 and arXiv:2012.10310 and some ongoing work.
