双子双势理论的规范表述

Gauge Formulation for Two Potential Theory of Dyons

O. P. S. Negi, H. Dehnen

摘要:

对偶电动力学和相应的麦克斯韦方程组(在存在的唯一)被重新从对偶性和规范不变性的对称性。相应地,从U(1)\times U(1)规范对称性出发,发展了双子广义电磁场的显协变、对偶对称和规范不变的二势理论。从U(1)\times U(1)规范对称性的拉格朗日公式出发,导出了相应的场方程和运动方程,证明了双子的两个四势。

英文摘要:

Dual electrodynamics and corresponding Maxwell's equations (in the presence of monopole only) are revisited from the symmetry of duality and gauge invariance. Accordingly, the manifestly covariant, dual symmetric and gauge invariant two potential theory of generalized electromagnetic fields of dyons has been developed consistently from U(1)\times U(1) gauge symmetry. Corresponding field equations and equation of motion are derived from Lagrangian formulation adopted for U(1)\times U(1) gauge symmetry for the justification of two four potentials of dyons.
