具有隐局域对称性的冷压缩重子物质与全息

Cold Compressed Baryonic Matter with Hidden Local Symmetry and Holography

Mannque Rho

摘要:

我描述了一个新的相结构的冷稠密重子物质预测在一个隐藏的本地对称性方法锚定规范理论和全息对偶方法的基础上的Sakai-Sugimoto模型的弦论。这个新相在引力扇区中被具有半瞬子量子数的重子占据,它与规范扇区中的半skyrmion是对偶的,在规范扇区中恢复了手征对称性,而轻夸克强子处于色限相.我们认为,在高于正常核物质密度而低于或处于手征恢复点的密度下变化的这种相,对高密度下强子的性质,特别是对核子间的短程相互作用,例如,短距离的多体力和强子--特别是K介子--在稠密介质中传播。对致密恒星结构的潜在重要影响将被预测。

英文摘要:

I describe a novel phase structure of cold dense baryonic matter predicted in a hidden local symmetry approach anchored on gauge theory and in a holographic dual approach based on the Sakai-Sugimoto model of string theory. This new phase is populated with baryons with half-instanton quantum number in the gravity sector which is dual to half-skyrmion in gauge sector in which chiral symmetry is restored while light-quark hadrons are in the color-confined phase. It is suggested that such a phase that aries at a density above that of normal nuclear matter and below or at the chiral restoration point can have a drastic influence on the properties of hadrons at high density, in particular on short-distance interactions between nucleons, e.g., multi-body forces at short distance and hadrons -- in particular kaons -- propagating in a dense medium. Potentially important consequences on the structure of compact stars will be predicted.
