论文摘要
我们计算了三维金茨堡 - 兰道的所有扰动r额相互作用的重新归一化组流,这些相互作用是三种量子量子染色体动力学的手性相变的潜力。与普遍的信念相反,我们发现系统中能够描述红外线中的二阶相变的固定点。这表明对过渡顺序的长期假设可能是错误的。如果过渡确实是二阶的,我们的结果可能会暗示轴向$ u(1)$对称性在过渡温度恢复。
We calculate the renormalization group flows of all perturbatively renormalizable interactions in the three-dimensional Ginzburg-Landau potential for the chiral phase transition of three-flavor quantum chromodynamics. On the contrary to the common belief we find a fixed point in the system that is able to describe a second-order phase transition in the infrared. This shows that long-standing assumptions on the transition order might be false. If the transition is indeed of second-order, our results may hint that the axial $U(1)$ symmetry restores at the transition temperature.
