在未来的电子-离子对撞机上，人们可以在电子-核碰撞中探索大量的物理程序。碰撞几何在这些研究中是非常重要的，而在以前的核深非弹性散射实验中很少讨论逐事件几何控制的测量。本文旨在提供一些详细的研究，通过前向中子多重性测量与零度量能器的碰撞几何标记的潜力。这种类型的几何处理，如果实现，可以是非常有益的约束核效应的电子-核程序在电子-离子对撞机。
There are a large number of physics programs one can explore in electron-nucleus collisions at a future electron-ion collider. Collision geometry is very important in these studies, while the measurement for an event-by-event geometric control is rarely discussed in the prior deep-inelastic scattering experiments off a nucleus. This paper seeks to provide some detailed studies on the potential of tagging collision geometries through forward neutron multiplicity measurements with a zero degree calorimeter. This type of geometry handle, if achieved, can be extremely beneficial in constraining nuclear effects for the electron-nucleus program at an electron-ion collider.
