超周边碰撞正向中子的generator：$\textbf{n$ \mathbf{_O^O} $n}$
A generator of forward neutrons for ultra-peripheral collisions: $\textbf{n$\mathbf{_O^O}$n}$
摘要：
近年来，RHIC和LHC重核碰撞中的光致反应研究已成为这两个装置研究计划的一个重要方向。特别是在超周边碰撞（UPC）中矢量介子的产生已经得到了深入的研究。由于强烈的光子通量，参与这种过程的两个原子核发生电磁离解，以束流速度产生中子。在这里，我们介绍$\textbf{n$ \mathbf{_O^O} $n}$（发音中午）蒙特卡罗程序，它产生的事件包含这样的中子。$\textbf{n$ \mathbf{_O^O} $n}$是一个基于ROOT的程序，可以与UPC中现有的矢量介子产生发生器或这种光核过程的理论计算相接口。$\textbf{n$ \mathbf{_O^O} $n}$也可以很容易地与RHIC和LHC实验的模拟程序集成。
英文摘要：
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. $\textbf{n$\mathbf{_O^O}$n}$ is a ROOT based program that can be interfaced with existing generators of vector meson production in UPC or with theoretical calculations of such photonuclear processes. $\textbf{n$\mathbf{_O^O}$n}$ can also be easily integrated with the simulation programs of the experiments at RHIC and the LHC.
