SuperCHIC: Monte Carlo Event Generator for Central Exclusive Production

The enclosed standalone Fortran code provides public access to the Monte Carlo generator described in:

arXiv:1005.0695 [hep-ph].

Please reference these papers if you use the programme for a publication.

The program currently generates weighted events for central exclusive γγ, χqJ and ηq production, with q=(b,c) and J=(0,1,2).

The decay of χcJ states is generated via the transition

χc → J/ψ γ → μ+ μ- γ

and χbJ via

χb → ϒ γ → μ+ μ- γ

Alternatively, χqJ and ηq decays can be generated via the two body transition

X → h1 + h2

with h(1,2) scalar or fermionic states of mass mh.

All processes can be generated at cms energies of s = 1.96, 7, 10 and 14 TeV and χcJ production can also be generated at s= 500 GeV.
