脉冲星:具有3味对称性的巨核

Pulsars: Macro-nuclei with 3-flavour symmetry

Renxin Xu

摘要:

一颗类似脉冲星的致密星是超新星爆发后留下的残余,在那里正常的重子物质被引力强烈压缩,但是由于基色相互作用的非微扰性质,这种压缩的重子物质的真实状态仍然没有得到很好的理解。我们认为,夸克可能是夸克团的凝聚态物质,即,与传统的中子星和夸克星不同的“夸克团星”。与2味对称的微核相比,夸克团星可以简单地看作是具有3味对称性的巨核。简要介绍了理论和观测方面的最新研究成果。

英文摘要:

A pulsar-like compact star is the rump left behind after a supernova where normal baryonic matter is intensely compressed by gravity, but the real state of such compressed baryonic matter is still not well understood because of the non-perturbative nature of the fundamental color interaction. We argue that pulsars could be of condensed matter of quark clusters, i.e., "quark-cluster stars" which distinguish from conventional neutron and quark stars. In comparison with 2-flavour symmetric micro-nuclei, a quark-cluster star could simply be considered as a macro-nucleus with 3-flavour symmetry. New research achievements both theoretical and observational are briefly presented.
