双轻子夸克-胶子等离子体中QCD和矢量介子的理论评述

Theoretical Review on QCD and Vector Mesons in Dileptonic Quark Gluon Plasma

Vlasios Petousis

摘要:

自量子色动力学(QCD)被发现以来,人们对超相对论重离子碰撞中的物理问题进行了大量的实验和理论研究。本文的基本目标是在R.Rapp和J.Wambach的杰出工作的基础上,对强相互作用的基本理论作一个简短的介绍,重点介绍光矢量介子。今天,人们普遍认为,解除禁闭和手征对称性恢复可能发生在一个热的和密集的强子介质,因为这在这些碰撞产生。我们的研究重点是通过对来自光矢量介子的双轻子产生的研究来检验新的物质形式,即所谓的夸克-胶子等离子体(QGP)。自去年以来,已经取得了重大进展,但在非微扰质量区仍然存在一些悬而未决的问题。

英文摘要:

After the discovery of the Quantum Chromodynamics (QCD), many experimental and theoretical efforts have been made to investigate physics issues involved in ultra relativistic heavy-ion collisions. The fundamental goal of this work is to present a short guide of the underlying theory of strong interactions with emphasis on the light vector mesons based on the exceptional work of R.Rapp and J.Wambach. Today widely believed that deconfinement and chiral symmetry restoration probably takes place in a hot and dense hadronic medium as this produced at these collisions. We focus at the place where the examination of the new form of matter, so-called Quark Gluon Plasma (QGP), can be done through the investigation of the dileptonic production coming from light vector mesons. Significant progress has been made since the last years, but still some open questions remain at the non-perturbative mass region.
