Dear Ercan,

PHOJET is available from www-ik.fzk.de/~engel an can be used to simulate the
hadron production in e+e- collisions by two-photon exchange. This is the
dominant interaction channel at high energy, at low energy also e+e-
annihilation is important (which is not treated in PHOJET).

Integration in FLUKA is probably not the ideal way to go. I would recommend
you use PHOJET as a separate program to first generate the particles of e+e-
interactions and write them to a file. Using FLUKA, you can read these
particle files and put them in the FLUKA stack and continue the standard way
with the FLUKA simulation. This is what was done for the linear collider
study
published in the Proceedings of the SARE meeting 1995, see attachment. The
reference is
A.\ Ferrari, R.P.\ Sala, R.\ Engel and J.\ Ranft:
{\it Radiation problems at $e^+ e^-$ linear colliders},
proceedings of the Workshop on Simulating
Accelerator Radiation Environments (SARE), (CERN/TIS-RP/97-05),
edited by G.R. Stevenson, CERN, Switzerland 1995, p. 80.

In PHOJET you can specify the beam energy, tagging conditions, and the
rage of
the invariant mass of the two-photon system. If would be good to declare most
particles as stable an let FLUKA do the tracking and decay of the particles.

I hope this helps you to get started with the simulations.

Best regards,
Ralph
