有限夸克质量零温夸克物质的状态方程

Equation of state of zero-temperature quark matter with finite quark masses

A. Vuorinen

摘要:

我们概述了最近的一个计算的关键要素,旨在确定在零温度和高密度下,使用有限夸克质量的退禁闭(但未配对)夸克物质的状态方程。计算是在微扰理论中进行的,最多可达三个循环,因此需要开发和应用一些新的计算工具。在这次演讲中,我们将介绍这些新技术的基本特征,并回顾在微扰论中考虑有限夸克质量效应的主要动机来源。

英文摘要:

We outline the key elements of a recent calculation aimed at determining the equation of state of deconfined (but unpaired) quark matter at zero temperature and high density, using finite quark masses. The computation is performed in perturbation theory up to three loops, and necessitates the development and application of some novel computational tools. In this talk, we introduce the basic features of these new techniques and review the main sources of motivation for considering finite quark mass effects in perturbation theory.
