Exploring Partially Confined Phases
摘要：
在SU（N）规范理论中，整体Z（N）对称性自发破缺为子群Z（L）的相可以通过在规范作用量中加入适当的Wilson线项来实现。这些相位是部分限制的，在这个意义上，夸克被限制，但束缚态的L夸克没有。在比正常解除禁闭温度大的温度下，相图、压力、弦张力和't Hooft环表面张力可以用解析法计算。对于弦张力和表面张力，近似的标度律自然出现。
英文摘要：
Phases of SU(N) gauge theories in which the global Z(N) symmetry breaks spontaneously to a subgroup Z(L) can be realized by adding appropriate Wilson line terms to the gauge action. These phases are partially confining, in the sense that quarks are confined but bound states of L quarks are not. At temperatures large compared to the normal deconfinement temperature, the phase diagram, pressure, string tensions, and 't Hooft loop surface tensions can be calculated analytically. Approximate scaling laws emerge naturally for both string tensions and surface tensions.
