Minkowski空间QED2 +1中的手征对称性破缺和禁闭

Chiral Symmetry Breaking and confinement in Minkowski space QED2+1

V. Sauli, Z. Batiz

摘要:

在没有任何解析假设的情况下,我们在Minkowski空间中求解了梯形QED ~(2 +1)。所得到的复费米子传播子在无极点的意义上表现出禁闭。此外,我们将格林函数的时间欧几里德空间,其中我们表明,在特殊情况下的梯形QED 2 +1的解决方案是完全等价的闵可夫斯基之一。对Wick旋转的明显无效性作了简要的讨论。将动力学质量的红外值与其他已知方法进行比较,例如与标准欧几里得计算。

英文摘要:

Without any analytical assumption we solve the ladder QED2+1 in Minkowski space. Obtained complex fermion propagator exhibits confinement in the sense that it has no pole. Further, we transform Greens functions to the Temporal Euclidean space, wherein we show that in the special case of ladder QED2+1 the solution is fully equivalent to the Minkowski one. Obvious invalidity of Wick rotation is briefly discussed. The infrared value of the dynamical mass is compared with other known approaches, e.g. with the standard Euclidean calculation.
