Máté Csanád, Dániel Kincses

AI总结:

本文综述从 SPS、RHIC 到 LHC 能区采用 Lévy 稳定源描述强子发射概率密度的飞秒干涉测量,并结合最新唯象与实验进展讨论其参数依赖及结果解释。

摘要:

飞秒干涉测量是研究超相对论碰撞中所产生物质时空几何的独特工具。如果对强子发射的概率密度分布进行参数化,就可以给出其参数对粒子动量、碰撞能量和碰撞几何的依赖关系。近年来,若干测量结果浮出水面,表明对上述分布采用 Lévy 稳定形状的假设是恰当的。与此同时,还出现了若干新的唯象进展,它们有助于解释实验结果,或为测量提供工具。在本文中,我们结合其中一些进展,包括唯象和实验方面的进展,讨论利用 Lévy 源开展飞秒干涉测量的重要方面。

英文摘要:

Femtoscopy is a unique tool to investigate the space-time geometry of the matter created in ultra-relativistic collisions. If the probability density distribution of hadron emission is parametrized, then the dependence of its parameters on particle momentum, collision energy, and collision geometry can be given. In recent years, several measurements came to light that indicated the adequacy of assuming a Lévy-stable shape for the mentioned distribution. In parallel, several new phenomenological developments appeared, aiding the interpretation of the experimental results or providing tools for the measurements. In this paper, we discuss important aspects of femtoscopy with Lévy sources in light of some of these advances, including phenomenological and experimental ones.
