Abstract: In the high-energy limit, the convergence of conventional perturbation theory is spoiled by large logarithms in s/|t| which can lead to substantial variations in the predictions for processes at the LHC . The High Energy Jets (HEJ) Monte Carlo event generator provides a flexible way to obtain greatly improved predictions for a number of phenomenologically important processes by resumming these logarithmic contributions to all orders in alpha_s. We present recent results obtained in this approach, in particular focusing on W-boson and same-sign W-pair production in association with jets at the LHC . We also discuss progress on extending this formalism beyond leading logarithmic accuracy.
