    • BH from photoproduction, used by ZEUS

GiBUU

(It may work on neutron also)
GiBUU does a good job with real photons on a proton (or heavier)
target.  It doesn't handle electroproduction as nicely (at least not the
last time I asked the Giessen group).
It is fairly straight forward to generate events, and there USED to be
good examples of input jobcards on the website, but they have been removed
recently while they upgrade.  I'd think the best route is to email them
directly to get the code and also ask for the example jobcards.

HEPGEN (Hard Exclusive Production GENerator) is a dedicated Monte Carlo generator of events, which is used for studies of hard exclusive leptoproduction processes at the COMPASS experiment kinematic domain. The studied reactions comprise both single photon production via Deeply Virtual Compton Scattering (DVCS) and Bethe-Heitler (BH) process as well as hard exclusive production of various mesons (HEMP). In addition to exclusive processes, HEPGEN allows also to generate events of single photon or meson production accompanied by the diffractive dissociation of the nucleon, which is one of the main sources of background in analyses of exclusive processes.
