Note: SpartyJet is now at HEPFORGE. The latest version and the relevant documentation can now be found there.

See also an earlier version of this program (lhc_jet) here; this is useful for those adverse to ROOT.  On this webpage, one can also find some data samples for inclusive jets at the LHC generated with Pythia and fed through the ATLAS topoclustering algorithm. The result is a list of 4-vectors that can be used as input for either version of the program. The samples go from minimum bias all the way to hard scatterings of 2 TeV/c and greater.
