New Predictions for Processes with >= 2 Jets at the LHC

The vast amount of data taken by the Large Hadron Collider (LHC) means it has become a precision experiment in very many channels. This is good news for sensitive tests of the Standard Model, but presents theory with a big challenge. Many effects which could be neglected at previous colliders now must be included to give a good description of data. One example of this is the logarithms in $\hat{s}/p_\perp$ which appear at all orders in alpha_s. The increase in centre-of-mass energy at the LHC both increases their numerical impact, and increases the phase space for the production of many jets with large transverse momentum, challenging standard fixed-order approaches. In this talk, I will describe how to perform a resummation of these logarithms in a fully flexible event generator, and illustrate the method with recent predictions for Higgs-plus-dijets, W+dijets and WW+dijets.
