DJpsiFDC: an event generator for the process $gg\to J\mathrm{/}\psi J\mathrm{/}\psi$ at LHC

DJpsiFDC is an event generator package for the process $gg\to J\mathrm{/}\psi J\mathrm{/}\psi$. It generates events for primary leading-order $2\to 2$ 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.
