标题： The Smile of Cheshire Cat At High Density

摘要： 在有限核、核物质和致密星体物质中，重子是通过QCD的猫式效应来描述的。 一种概念性的联系，尽管在数学严谨性上有所欠缺，是通过所谓的猫式原理来建立的。 用与QCD变量“对偶”的术语来说，进入极高密度时会暴露出量子霍尔液滴——或称薄饼——在此处达到标度不变极限点，其中$g_A\to 1$，$f_\pi\to f_\chi$——其中$f_\pi$和$f_\chi$分别是介子和标度子的衰变常数——以及重子宇称双重化得以实现。 这种情景暗示了一种迄今为止完全未被探索的高密度对偶重子物质结构，它既不需要也不排除在接近引力坍缩的致密星体核心中从强子到夸克的（快速）一阶相变。 显示英文摘要

摘要： Baryons in finite nuclei, nuclear matter and dense compact-star matter are described in terms of Cheshire Cat for QCD. A potential conceptual link, admittedly short in mathematical rigor, between their manifestations is made by what's called Cheshire Cat Principle. Put in terms taken ``dual" to QCD variables, going to very high density exposes quantum Hall droplets -- or pancakes -- at which the dilaton-limit fixed point with $g_A\to 1$, $f_\pi\to f_\chi$ -- where $f_\pi$ and $f_\chi$ are respectively the pion and dilaton decay constants -- and the baryon parity-doubling are reached. This scenario suggests a thus-far totally unexplored structure of dual baryonic matter at high density which does neither require nor rule out (rapid) first-order phase transitions from hadrons to quarks in the core of compact stars on the verge of gravitational collapse.
