摘要翻译:
q态Potts场论描述了与q色置换对称性自发破缺有关的普适类。在二维中,它被定义为Q=4,在没有磁场的情况下,它在远离临界温度的地方表现出对偶性和可积性。我们展示了当一个磁场被打开时,它是如何提供一个最简单的限制模型,同时允许介子和重子。解束缚夸克(扭结)存在于一个以一级跃迁和二级跃迁为边界的相中。讨论了质谱随温度和磁场的变化规律。

英文摘要:
The q-state Potts field theory describes the universality class associated to the spontaneous breaking of the permutation symmetry of q colors. In two dimensions it is defined up to q=4 and exhibits duality and integrability away from critical temperature in absence of magnetic field. We show how, when a magnetic field is switched on, it provides the simplest model of confinement allowing for both mesons and baryons. Deconfined quarks (kinks) exist in a phase bounded by a first order transition on one side, and a second order transition on the other. The evolution of the mass spectrum with temperature and magnetic field is discussed.
