暗单极与SL(2,Z)对偶

Dark Monopoles and SL(2,Z) Duality

John Terning, Christopher B. Verhaaren

摘要:

我们探讨两个阿贝尔规范理论,既有电和磁荷之间的动力学混合。当其中一个光子变得有质量时,低能有效理论中会出现新的效应,包括狄拉克电荷量子化的失败,因为来自一个扇区的粒子与另一个扇区的光子获得参数小的耦合。我们在整个分析中保持了一个明显的SL(2,Z)对偶,它是两个非混合规范理论对偶的对角子群。

英文摘要:

We explore kinetic mixing between two Abelian gauge theories that have both electric and magnetic charges. When one of the photons becomes massive, novel effects arise in the low-energy effective theory, including the failure of Dirac charge quantization as particles from one sector obtain parametrically small couplings to the photon of the other. We maintain a manifest SL(2,Z) duality throughout our analysis, which is the diagonal subgroup of the dualities of the two un-mixed gauge theories.
