论文摘要
深色光子作为超轻暗物质候选者可以通过动力学混合与标准模型颗粒相互作用。我们建议使用带有太阳观测的射电望远镜搜索超轻的暗光子暗物质。暗光子暗物质可以有效地在太阳大气的最外部区域，即太阳电晕的最外部区域，其中光子的血浆质量接近深色光子静止质量。由于强烈的共振转化并从太阳与地球之间的短距离中受益，射电望远镜可以导致深色光子搜索敏感性在$ 4 \ times 10^{ - 8} -4 \ times 10^{ - 6} { - 6} { - 6} \，\ rm {ev} $中，对应于频率$ 10-1000 \，作为一个有前途的例子，操作射电望远镜Lofar可以在1（100）小时的太阳能观察中到达动力学混合$ε\ sim \ sim 10^{ - 13} $（$ 10^{ - 14} $）。未来的实验SKA阶段1可以达到$ε\ sim 10^{ - 16} -10^{ - 14} $，并带有$ 1 $小时的太阳能观测。
Dark photon as an ultralight dark matter candidate can interact with the Standard Model particles via kinetic mixing. We propose to search for the ultralight dark photon dark matter using radio telescopes with solar observations. The dark photon dark matter can efficiently convert into photons in the outermost region of the solar atmosphere, the solar corona, where the plasma mass of photons is close to the dark photon rest mass. Due to the strong resonant conversion and benefiting from the short distance between the Sun and the Earth, the radio telescopes can lead the dark photon search sensitivity in the mass range of $4 \times 10^{-8} - 4\times 10^{-6} \, \rm{eV}$, corresponding to the frequency $10 - 1000 \, {\rm MHz}$. As a promising example, the operating radio telescope LOFAR can reach the kinetic mixing $ε\sim 10^{-13}$ ($10^{-14}$) within 1 (100) hour solar observations. The future experiment SKA phase 1 can reach $ε\sim 10^{-16} - 10^{-14}$ with $1$ hour solar observations.
