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

TL;DR

DJpsiFDC is a Fortran-based event generator designed for simulating the production of J/psi pairs via gluon fusion at the LHC, facilitating integration into detector simulations.

Contribution

It introduces a dedicated event generator for the $gg\to J/\psi J/\psi$ process, enabling accurate simulation of this specific production channel.

Findings

Generates events for $gg\to J/\psi J/\psi$ at leading order

Produces LHE files compatible with detector simulations

Implemented in Fortran for ease of integration

Abstract

DJpsiFDC is an event generator package for the process $gg\to J/\psi J/\psi$. 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.
