在二维空间中的三态波茨场理论，在热扰动和磁扰动下，提供了最简单的禁闭模型，既考虑了介子和重子，也考虑了带有退禁闭夸克的扩展相。我们数值研究了该模型的质谱在其整个参数范围内的演变，得到了一个模式的约束，粒子衰变和相变，证实了最近的预测。
The three-state Potts field theory in two dimensions with thermal and magnetic perturbations provides the simplest model of confinement allowing for both mesons and baryons, as well as for an extended phase with deconfined quarks. We study numerically the evolution of the mass spectrum of this model over its whole parameter range, obtaining a pattern of confinement, particle decay and phase transitions which confirms recent predictions.
