A generator of forward neutrons for ultra-peripheral collisions: $\textbf{n$\mathbf{_O^O}$n}$

Understand

The study of photon-induced reactions in collisions of heavy nuclei at RHIC and the LHC has become an important direction of the research program of these facilities in recent years.

• In particular, the production of vector mesons in ultra-peripheral collisions (UPC) has been intensively studied.
• Owing to the intense photon fluxes, the two nuclei participating in such processes undergo electromagnetic dissociation producing neutrons at beam rapidities.
• Here, we introduce the $\textbf{n$\mathbf{_O^O}$n}$ (pronounced noon) Monte Carlo program, which generates events containing such neutrons.
