狄拉克中微子磁矩和消失电荷的规范无关性：一个精确的单圈证明
Gauge Independence of Magnetic Moment and Vanishing Charge of Dirac Neutrinos: an Exact One-loop Demonstration
摘要：
狄拉克中微子的磁矩和消失的电荷是物理上可观测的量，在相容的量子场论中，它们不依赖于规范的选择。我们在最小扩展标准模型的R_xi和酉规范中的单圈水平上明确地验证了这一说法。我们通过直接处理循环积分的被积函数和使用简单的代数恒等式和积分关系来实现这一点。我们的结果一般适用于任何质量的相关粒子和幺正中微子混合。
英文摘要：
The magnetic moment and vanishing charge of a Dirac neutrino are physically observable quantities and must not depend on the choice of gauge in a consistent quantum field theory. We verify this statement explicitly at the one loop level in both R_xi and unitary gauges of the minimally extended standard model. We accomplish this by manipulating directly the integrands of loop integrals and employing simple algebraic identities and integral relations. Our result generally applies for any masses of the relevant particles and unitary neutrino mixing.
