双味夸克QCD Phase Diagram中的临界点

Critical Points in the QCD Phase Diagram with Two Flavors of Quarks

J. I. Kapusta, E. S. Bowman

摘要:

本文采用线性西格玛模型研究了有限温度和密度下两种夸克的手征动力学。我们的计算包括了玻色子场和费米子场的热涨落。特别是,我们确定的温度和重子化学势作为一个函数的π介子质量的平面中的相图。一个有趣的相结构发生,结果在零,一个或两个临界点取决于真空π介子质量的值。

英文摘要:

We employ the linear sigma model to study the chiral dynamics of two flavors of quarks at finite temperature and density. Our calculations include thermal fluctuations of both the bosonic and fermionic fields. In particular, we determine the phase diagram in the plane of temperature and baryon chemical potential as a function of the pion mass. An interesting phase structure occurs that results in zero, one, or two critical points depending on the value of the vacuum pion mass.
