I am simulating a thin target setup in which a 11 GeV e- beam impinges on a tunsgten target (target length ~ 0.1% X0). I am interested in simulating the production of muon pairs.
Since the target thickness is so small, I think that an important contribution (possibly, the dominant one?) comes from direct electro-production of the muon pair, mediated by a virtual photon, rather than by the dual process involving the production of a Bremmstrahlung photon and its conversion to a muon pair.
May I ask you if this electro-production process is implemented currently in FLUKA?
