在e+e碰撞中满足集体性的最小条件吗?
Are minimal conditions for collectivity met in e+e- collisions?
摘要:
集体行为的特征已经在高度相对论性的p+p碰撞,以及在p+A,d+A和3 He +A碰撞中测量到。在这些系统中的许多粒子相关测量已成功地描述了粘性流体动力学和传输模型的基础上的计算。这些观察提出了一个系统表现集体性的最低必要条件的问题。最近,许多科学家提出了一个问题,即在e+e-碰撞中产生的夸克和胶子是否可以满足这些最小条件。在本文中,我们探讨可能的签名集体,或缺乏,在电子+电子碰撞利用多相输运(AMPT)框架,其中包括熔化的色弦,部分子散射,强子化,强子再散射。
英文摘要:
Signatures of collective behavior have been measured in highly relativistic p+p collisions, as well as in p+A, d+A, and 3He+A collisions. Numerous particle correlation measurements in these systems have been successfully described by calculations based on viscous hydrodynamic and transport models. These observations raise the question of the minimum necessary conditions for a system to exhibit collectivity. Recently, numerous scientists have raised the question of whether the quarks and gluons generated in e+e- collisions may satisfy these minimum conditions. In this paper we explore possible signatures of collectivity, or lack thereof, in e+e- collisions utilizing A Multi-Phase Transport (AMPT) framework which comprises melted color strings, parton scattering, hadronization, and hadron re-scattering.
