PHOBOS Glauber Monte Carlo

The PHOBOS Glauber Monte Carlo

B. Alver, M. Baker, C. Loizides, P. Steinberg

摘要:

"Glauber"模型用于计算重离子碰撞初始状态下的几何量,如碰撞参量、参与碰撞的核子数和初始偏心率。四个RHIC实验对Glauber模型的计算方法不同,导致对各种几何观测量的结果相似。在本文中,我们描述了一个基于蒙特卡罗的Glauber模型计算的PHOBOS实验的实现。描述了计算中的假设。提供了用于运行各种计算的用户指南。

英文摘要:

``Glauber'' models are used to calculate geometric quantities in the initial state of heavy ion collisions, such as impact parameter, number of participating nucleons and initial eccentricity. The four RHIC experiments have different methods for Glauber Model calculations, leading to similar results for various geometric observables. In this document, we describe an implementation of the Monte Carlo based Glauber Model calculation used by the PHOBOS experiment. The assumptions that go in the calculation are described. A user's guide is provided for running various calculations.
