Simulation of jets at colliders

We review the development of the physics behind event generators during the last decade. After a more general description of parton showers, we focus mostly on the perturbative side of the simulations. Two newer developments of parton showers, as implemented in HERWIG++, are described in greater detail. Matching and merging of parton showers with fixed order computations are discussed. We describe some developments of multiple partonic interactions which are relevant for the simulation of jets from the underlying event, where the implementation in HERWIG++ is again taken as a generic example. Finally, we compare some event generator results to collider data from LEP and the LHC. (C) 2013 Elsevier B.V. All rights reserved.
