DJpsiFDC: an event generator for the process $ggto J/psi J/psi$ at LHC

DJpsiFDC is an event generator package for the process $ggto J/psi J/psi$. It generates events for primary leading-order $2to 2$ processes. The package could generate a LHE document and this document could easily be embedded into detector simulation software frameworks. The package is produced in Fortran codes.
