太阳盆地中的暗光子

Dark Photons in the Solar Basin

Robert Lasenby, Ken Van Tilburg

摘要:

太阳内部暗光子的产生是在大质量范围内探测这种粒子的最灵敏探测器的基础。一小部分暗光子被发射到引力束缚的轨道上,形成了一个“太阳盆地”,在天体物理学上存活了很长时间。我们表明,这个人口可能会导致现有的和拟议的暗物质探测实验中的信号,开辟了重要的新的参数空间独立于暗光子是否构成的暗物质。即使在保守的假设下,当前暗物质实验的结果已经限制了新的参数空间;在基准假设下,太阳盆地中的暗光子数量可能是XENON 1 T中观察到的过量事件的原因。未来的低阈值实验可能会对这些太阳系束缚的暗光子敏感到亚电子伏特的质量,在低于电流限制的耦合数量级。

英文摘要:

Production of dark photons inside the Sun forms the basis for the most sensitive probes of such particles over a wide mass range. A small fraction of dark photons is emitted into gravitationally bound orbits, building up a "Solar basin" population that survives for astrophysically long times. We show that this population could lead to signals in existing and proposed dark matter detection experiments, opening up significant new parameter space independent of whether dark photons make up the dark matter. Even with conservative assumptions, results from current dark matter experiments already constrain new parameter space; with fiducial assumptions, a Solar basin population of dark photons could be responsible for excess events seen in XENON1T. Future low-threshold experiments could be sensitive to these Solar-System-bound dark photons down to sub-eV masses, at couplings orders of magnitude below current constraints.
