Please reference the above papers and refer to "JHU generator" when using the simulation program and "MELA" when using the matrix element likelihood approach. The latter was also introduced in [12]. The matrix element package (MELA) also depends on MCFM libraries for background parameterization which should be referenced [3] when used. A more recent version also provides interface to MadGraph [4] and SMEFTsim [5].

Generator for pp → X → VV, VBF, X+JJ, pp → VX, ee → VX

A generator giving parton-level information including full spin and polarization correlations for the processes ab → X → VV (V=Z,W,gamma), VBF, X+JJ, pp → VX, ee → VX. The Fortran program produces a single-produced X resonance via either the gluon fusion, qqbar, VBF, or VH processes for either the Tevatron, the LHC, or an e+e- collider. The resonance X can be a spin-zero, -one, or -two particle with general couplings defined in the study. The output is in the LHE format and can be input to any parton showering program. Please see the manual file for further technical details.
