摘要:

在四维四费米子模型中,我们研究了有限温度下Lorentz对称性和CPT对称性的动力学恢复。我们评估的间隙方程在零和有限的温度下,并观察到,根据理论的参数,有一个临界温度,在该温度下的洛伦兹和CPT对称性恢复。

英文摘要:

In a 4D four-fermion model we study the dynamical restoration of Lorentz and CPT symmetries at finite temperature. We evaluate the gap equation both at zero and at finite temperature and observe that, depending on the parameters of the theory, there is a critical temperature at which the Lorentz and CPT symmetries are restored.
