论文摘要
太阳内的深色光子的产生构成了此类颗粒最敏感探针在广泛质量范围内的基础。一小部分的深色光子发射到了重力结合的轨道中，建立了一个“太阳能盆地”种群，该轨道可为天体物理长期生存。我们表明，该人群可能导致现有和拟议的暗物质检测实验中的信号，从而开放了重要的新参数空间，而与暗光子是否构成暗物质。即使有了保守的假设，目前的暗物质实验的结果已经限制了新的参数空间。有了基准假设，黑暗光子的太阳能盆地种群可能导致异种1T中看到的过剩事件。未来的低阈值实验可能会对这些太阳系结合的暗光子敏感到sub-ev质量，在耦合级以下，低于当前约束的数量级。
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.
