冷压缩重子物质的有效场论

Toward an Effective Field Theory for Cold Compressed Baryonic Matter

Won-Gi Paeng, Mannque Rho

摘要:

这是第一作者(W。G. P.)第二作者(M.R.)作为“极端条件下的强子物质”系列的第一部分,这是WCU汉阳计划的主要主题。它涵盖了在QCD的有效场论的框架内,从零密度到核物质密度以及稍微超过核物质密度的尝试,最终目标是达到与致密星相关的密度,包括手征相变和夸克物质。重点是概念方面,而不是详细“拟合”正在运行的放射性离子束机器和项目(如韩国的“KorIA”)中处理的物理学类型的数据,并将在FAIR/GSI等即将推出的加速器上进行探索。这里提出的方法是基本上不同于标准的文献中发现的隐藏的局部对称性的概念-这是手征对称性的强相互作用-和它的推广到双重引力描述涉及无限塔的隐藏规范场密切依赖。

英文摘要:

This is an extended version of the note taken by the first author (W.-G.P.) on a lecture given by the second author (M.R.) as a first part of the series on "Hadronic Matter Under Extreme Conditions," the principal theme of the WCU-Hanyang Program. It covers the attempts to go in a framework anchored on effective field theory of QCD from zero density to the nuclear matter density and slightly beyond, with the ultimate goal of arriving at the density relevant to compact stars, including chiral phase transition and quark matter. The focus is on the conceptual aspects rather than detailed "fitting" of the data on the kinds of physics that are being addressed to in radioactive-ion-beam machines in operation as well as in project (such as `KoRIA' in Korea) and will be explored at such forthcoming accelerators as FAIR/GSI. The approach presented here is basically different from the standard ones found in the literature in that the notion of hidden local symmetry -- which underlies the chiral symmetry of the strong interactions -- and its generalization to dual gravity description involving infinite tower of hidden gauge fields are closely relied on.
