SuperCHIC: Monte Carlo Event Generator for Central Exclusive Production

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

Please reference this paper if you use the programme for a publication.

The programme currently generates weighted events for central exclusive γγ production, χ_c0, χ_c1 and χ_c2 production via the decay chain:

χ_c → J/ψ γ → μ⁺ μ^- γ

and χ_b0, χ_b1 and χ_b2 production via the equivalent decay chain:

χ_b → ϒ γ → μ⁺ μ^- γ

χ_c and χ_b events can be generated at cms energies of √s = 1.96 TeV and √s = 14 TeV. γγ events can currently be generated at √s= 1.96 TeV only. Code for other cms energies can be provided on request.
