Title: 总带电粒子产率在LHC下O+O和Ne+Ne碰撞中的中心度依赖性的修改Glauber模型预测

Abstract: In this article we present the results of application of the Monte Carlo modified Glauber model for the predictions of collision centrality dependence of the total charged-particle yields for 16O +16O and 20Ne+20Ne colliding systems at the LHC. Our model differs from the Standard Glauber model by the effective account of the energy losses in successive inelastic nucleon-nucleon collisions. For this purpose, a single model parameter k is defined as a mean fraction of the momentum loss that happens in any binary nucleon collision due to the production of multiple particles. Therefore, the decrease of the nucleon momentum after each inelastic collision leads to a corresponding reduction of the inelastic cross section and the mean multiplicity yield in the subsequent interaction. All these effects are taken into account in the MC model in each of the subsequent inelastic binary interactions. We discuss the purely geometrical effects for these light colliding systems that could be considered useful in future studies of QGP properties in energy density scanning. Predictions in this single parameter model are based on the previous successful analysis of non-linear centrality dependence of charged particle yields observed in Pb+Pb collisions by ALICE at the LHC.

Abstract: 在本文中，我们介绍了蒙特卡罗修正的Glauber模型在预测16O +16O和20Ne+20Ne碰撞系统在LHC中的总带电粒子产率的碰撞中心度依赖性的应用结果。 我们的模型与标准Glauber模型的不同之处在于，它有效地考虑了在连续的非弹性核子-核子碰撞中的能量损失。 为此，定义了一个单一的模型参数k，作为任何二元核子碰撞中由于多粒子产生而导致动量损失的平均分数。 因此，每次非弹性碰撞后核子动量的减少会导致后续相互作用中非弹性截面和平均粒子产率的相应减少。 所有这些效应都在MC模型中，在每一次后续的非弹性二元相互作用中都被考虑进去。 我们讨论了这些轻质量碰撞系统中的纯几何效应，这些效应可能在将来研究QGP性质的能量密度扫描中有用。 这个单一参数模型的预测基于ALICE在LHC上对Pb+Pb碰撞中观察到的带电粒子产率非线性中心度依赖性的先前成功分析。
