Multiple Jets at the LHC with High Energy Jets
  We present a flexible Monte Carlo implementation of the perturbative framework of High Energy Jets, describing multi-jet events at hadron colliders. The description includes a resummation which ensures leading logarithmic accuracy for large invariant mass between jets, and is matched to tree-level accuracy for multiplicities up to 4 jets. The resummation includes all-order hard corrections, which become important for increasing centre-of-mass energy of the hadronic collision.   We discuss observables relevant for confronting the perturbative framework with 7 TeV data from the LHC, and the impact of the perturbative corrections on several dijet and trijet observables which are relevant in the search for new physics.
