Abstract

We present HEJ 2, a new implementation of the High Energy Jets formalism
for high-energy resummation in hadron-collider processes as a exible Monte
Carlo event generator. In combination with a conventional xed-order event
generator, HEJ 2 can be used to obtain greatly improved predictions for
a number of phenomenologically important processes by adding all-order
logarithmic corrections in ^s=p2?. A prime example for such a process is the
gluon-fusion production of a Higgs boson in association with widely separated
jets, which constitutes the dominant background to Higgs boson production
in weak-boson fusion.
