平均场方法研究具有矢量相互作用的风味相似性

Mean field approach to flavor susceptibilities with a vector interaction

L. Ferroni, V. Koch

摘要:

我们表明,味对角和非对角的轻夸克在消失的化学势的磁化率可以计算一致假设重子密度和同位旋密度的QCD的依赖表示的矢量-isoscillator和矢量-isovector耦合,分别。在平均场水平上,它们的表达式只依赖于有效的介质依赖耦合和夸克热力学势。耦合的强度,然后可以估计从模型使用格点量子色动力学数据作为输入。

英文摘要:

We show that flavor diagonal and off-diagonal susceptibilities of light quarks at vanishing chemical potential can be calculated consistently assuming the baryon density and isospin density dependence of QCD to be expressed by a vector-isoscalar and a vector-isovector coupling, respectively. At the mean field level, their expression depends only on the effective medium-dependent couplings and quark thermodynamic potential. The strength of the couplings can be then estimated from the model using lattice QCD data as an input.
