论文摘要
通过违反均匀的电磁背景领域的奇偶校验，对通过轴向病房的身份进行了异常的手性，并通过轴向病房的身份及其对Schwinger机制的依赖性进行了质量影响。真空渐近状态在期望值的解释中起作用。讨论的是，使用散射矩阵元素计算出的可观察物可以预测欧几里得平衡下的情况。其中一个显着的后果是手性异常的消失。相比之下，讨论了在内部或实时形式主义下计算出的可观察到的物体，预测场景不平衡，并捕获由于施温格机制而导致的平均产生的粒子抗粒子对的影响。平衡性手性异常被补充了施温格机制所预期的指数二次质量抑制。审查了包括手性磁效应和手性冷凝物在内的应用中的类似行为。
The anomalous generation of chirality with mass effects via the axial Ward identity and its dependence on the Schwinger mechanism is reviewed, utilizing parity violating homogeneous electromagnetic background fields. The role vacuum asymptotic states play on the interpretation of expectation values is examined. It is discussed that observables calculated with an in-out scattering matrix element predict a scenario under Euclidean equilibrium. A notable ramification of which is a vanishing of the chiral anomaly. In contrast, it is discussed observables calculated under an in-in, or real-time, formalism predict a scenario out-of equilibrium, and capture effects of mean produced particle anti-particle pairs due to the Schwinger mechanism. The out-of equilibrium chiral anomaly is supplemented with exponential quadratic mass suppression as anticipated for the Schwinger mechanism. Similar behavior in and out-of equilibrium is reviewed for applications including the chiral magnetic effect and chiral condensate.
