强子物质的Phase Diagram

The Phase Diagram of Hadronic Matter

P. Castorina, K. Redlich, H. Satz

摘要:

我们用强子的基本动力学和几何学特征解释了强子物质的相结构。通过增加温度T或重力化学势μ来增加有限空间延伸的组分的密度,最终“填满盒子”并消除物理真空。我们通过渗流理论确定了相应的跃迁作为T和μ的函数。在低重子密度下,这意味着重叠的介子袋融合成一个大袋,而在高重子密度下,硬核排斥限制了重子的空间移动性。因此,强子物质有两种不同的极限状态。我们比较我们的结果有效的手性模型研究。

英文摘要:

We interpret the phase structure of hadronic matter in terms of the basic dynamical and geometrical features of hadrons. Increasing the density of constituents of finite spatial extension, by increasing the temperature T or the baryochemical potential mu, eventually "fills the box" and eliminates the physical vacuum. We determine the corresponding transition as function of T and mu through percolation theory. At low baryon density, this means a fusion of overlapping mesonic bags to one large bag, while at high baryon density, hard core repulsion restricts the spatial mobility of baryons. As a consequence, there are two distinct limiting regimes for hadronic matter. We compare our results to those from effective chiral model studies.
