论文摘要

即将到来的电子离子对撞机(EIC)将解决现代核物理学的几个出色难题。可以通过研究高能量电子普罗顿($ ep $)和电子核核($ e $ a)碰撞来理解诸如核和核的党结构,质量和自旋的起源。实现EIC的科学目标将需要一个新型的电子撞针和能够执行高精度测量的探测器,还需要专门的工具来建模和解释数据。为了帮助后者,我们提出了蒙特卡洛(MC)发电机-Beagle的通用$ e $ e $ e $ e $ e $。在本文中,我们提供了集成到Beagle的模型的一般描述,Beagle在$ e $ a物理学中的应用,对EIC的探测器需求的影响以及基于可用的实验数据对Beagle中的参数调整。具体来说,我们专注于$ EP $和$ e $ a碰撞中粒子产生的模型和数据比较的选择,基线粒子分布提供了表征事件的重要信息。此外,我们研究了$ e $ a碰撞中的碰撞几何测定,可以用作改变核密度的实验工具。

The upcoming Electron-Ion Collider (EIC) will address several outstanding puzzles in modern nuclear physics. Topics such as the partonic structure of nucleons and nuclei, the origin of their mass and spin, among others, can be understood via the study of high energy electron-proton ($ep$) and electron-nucleus ($e$A) collisions. Achieving the scientific goals of the EIC will require a novel electron-hadron collider and detectors capable to perform high-precision measurements, but also dedicated tools to model and interpret the data. To aid in the latter, we present a general-purpose $e$A Monte Carlo (MC) generator - BeAGLE. In this paper, we provide a general description of the models integrated into BeAGLE, applications of BeAGLE in $e$A physics, implications for detector requirements at the EIC, and the tuning of the parameters in BeAGLE based on available experimental data. Specifically, we focus on a selection of model and data comparisons in particle production in both $ep$ and $e$A collisions, where baseline particle distributions provide essential information to characterize the event. In addition, we investigate the collision geometry determination in $e$A collisions, which could be used as an experimental tool for varying the nuclear density.
