The EPJPSI Monte Carlo for J/psi mesons in high energy gamma-p, e-p, p-p_bar and p-p collisions

 
 EPJPSI  is a program to simulate elastic and inelastic vector meson production in photo production and deep inelastic scattering.

NOTE:  The subroutines LMEPS, LPRIKT, LREMH, PYSSPA, PYREMN, PYSTFU for parton showers, remnant treatment and structure functions are copies from LEPTO 6.1  (G. Ingelman , DESY HERA Workshop (1991) 1366, G. Ingelman et al., Comp. Phys. Comm. 101 (1997) 108) and  PYTHIA 4.8  (H.U. Bengtsson, T. Sjostrand, Comp. Phys. Comm. 46 (1987) 43), which are modified for the use in EPJPSI.
