Abstract / Description of output

We present version 2.1 of the High Energy Jets (HEJ) Monte Carlo event generator. With the new version, high-energy logarithms can now be summed to all orders in processes with final-state leptons originating from a charged or neutral vector boson together with multiple jets, in addition to processes available in earlier versions. Furthermore, the resummation is extended to include an additional gauge-invariant class of next-to-leading logarithmic corrections. HEJ 2.1 can be obtained from https://hej.hepforge.org.
