Lorentz和CPT破坏电动力学中磁场的无接触项

No Contact Terms for the Magnetic Field in Lorentz- and CPT-Violating Electrodynamics

Karl Schober, Brett Altschul

摘要:

在违反洛伦兹和CPT的电动力学修正中,已知运动电荷的场具有不寻常的奇异性。这就提出了一个问题,即奇异行为是否可能包括$δ$函数接触项,类似于理想化偶极子领域中出现的接触项。然而,通过计算无限长直导线的磁场,我们证明了在运动点电荷的磁场中不存在这样的接触项

英文摘要:

In a Lorentz- and CPT-violating modification of electrodynamics, the fields of a moving charge are known to have unusual singularities. This raises the question of whether the singular behavior may include $δ$-function contact terms, similar to those that appear in the fields of idealized dipoles. However, by calculating the magnetic field of an infinite straight wire in this theory, we demonstrate that there are no such contact terms in the magnetic field of a moving point charge
