摘要

暗光子是标准模型之外的一种新的规玻色子，是暗物质（DM）的一种候选物质。暗光子暗物质（DPDM）通过动能混合与电磁场相互作用，这就意味着可以用银河系外的甚高能（VHE）源来进行约束。在这项工作中，我们试图从蓝星的宿主星系、星系际介质和银河系中的光子-暗光子散射过程来约束动能混合。来自蓝星的VHE光子会穿过超大质量黑洞周围的致密DM尖峰，在那里DPDM的吸收会显著增强。根据对马尔卡里安（Mrk）421和马尔卡里安501的观测，在95（\%\）置信水平下，动力学混合被约束为（\epsilon \sim 10^{-7}\），质量范围为（m_\textrm{D}\sim 0.03 {-} 1\）eV。

Constraining dark photon parameters based on the very high energy observations of blazars

Dark photon is a new gauge boson beyond the Standard Model as a kind of dark matter (DM) candidate. Dark photon dark matter (DPDM) interacts with electromagnetic fields via kinetic mixing, implicating an approach to give a constraint with extragalactic very high energy (VHE) sources. In this work, we attempt to constrain the kinetic mixing from the photon-dark photon scattering process in the host galaxy of blazar, the intergalactic medium and the Milky Way. The VHE photons from a blazar would pass through a dense DM spike around the supermassive black hole where the absorption from DPDM is dramatically enhanced. The kinetic mixing is constrained to be \(\epsilon \sim 10^{-7}\) at a 95\(\%\) confidence level with \(m_\textrm{D}\sim 0.03 {-} 1\) eV mass range from the observations of Markarian (Mrk) 421 and Mrk 501.
