有限夸克物质的M-F统计模型
Thomas-Fermi Statistical Models of Finite Quark Matter
摘要：
我介绍和讨论模型的有限夸克物质使用的形式主义的费米子-费米统计模型。与袋模型类似，引入真空能量项来模拟长距离约束，但即使没有这样的项，该模型也会从残余色库仑吸引力产生束缚态。我讨论了三个重子的应用：一个等质量的非相对论模型，有和没有体积压力，超相对论限制体积压力，和色味锁定无质量模型。这些模型可以推广到多介子和其它混合强子态。希望这能有助于更好地理解高多夸克态的现象学，为更详细的格点量子色动力学计算做准备。
英文摘要：
I introduce and discuss models of finite quark matter using the formalism of the Thomas-Fermi statistical model. Similar to bag models, a vacuum energy term is introduced to model long distance confinement, but the model produces bound states from the residual color Coulomb attraction even in the absence of such a term. I discuss three baryonic applications: an equal mass nonrelativistic model with and without volume pressure, the ultra-relativistic limit confined by volume pressure, and a color-flavor locking massless model. These model may be extended to multi-meson and other mixed hadronic states. Hopefully, it can help lead to a better understanding of the phenomenology of high multi-quark states in preparation for more detailed lattice QCD calculations.
