CLAS12 TCS (linearly polarized)

code

  • LPAIR
    • used by the experiments at DESY/HERA
  • Compton2.0
    • BH from photoproduction, used by ZEUS
  • GiBUU
    • gibuu.hepforge.org
(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.
