We present a new framework for calculating multi-jet observables through a resummation of hard emission. The framework is based on the high energy factorisation of amplitudes, with the region of applicability extended by constraining the analytic properties of the scattering amplitudes according to other known all-order results. As an example of application we study predictions for Higgs Boson production through gluon fusion at the LHC in association with at least two jets. The result is matched to the tree level matrix elements for 2 and 3 jet production, and implemented in a Monte Carlo generator.
