摘要:

超轻暗光子是引人注目的暗物质候选体之一。可见光子与暗光子之间的相互作用是通过标准模型和暗部门中阿贝尔规范群的场强张量之间的规范动力学混合引入的。在存在电和磁两种电荷的情况下,相对论电动力学被推广为量子电磁动力学(QEMD)。光子由对应于两个$U(1)$规范群的两个四势描述,并满足非平凡的交换关系。在本工作中,我们在QEMD框架下构建了低能暗光子-光子相互作用,并获得了新的暗光子-光子动力学混合。在此框架下推导了相应的场方程和新的麦克斯韦方程组。我们还研究了暗光子作为轻暗物质的探测策略,以及在射电望远镜实验中通用动力学混合的探测方法。

英文摘要:

The ultralight dark photon is one of intriguing dark matter candidates. The interaction between the visible photon and dark photon is introduced by the gauge kinetic mixing between the field strength tensors of the Abelian gauge groups in the Standard Model and dark sector. The relativistic electrodynamics was generalized to quantum electromagnetodynamics (QEMD) in the presence of both electric and magnetic charges. The photon is described by two four-potentials corresponding to two $U(1)$ gauge groups and satisfying non-trivial commutation relations. In this work, we construct the low-energy dark photon-photon interactions in the framework of QEMD and obtain new dark photon-photon kinetic mixings. The consequent field equations and the new Maxwell's equations are derived in this framework. We also investigate the detection strategies of dark photon as light dark matter as well as the generic kinetic mixings at haloscope experiments.
