论文摘要
太阳可能会产生假想的光颗粒，例如轴或深色光子，这种情况可以用所谓的螺旋镜实验探测。在这里，我们研究了太阳暗光子的角度和光谱分布对此类仪器灵敏度的影响。我们首次评估深色光子通量在整个质量范围内的光谱和角度依赖性，并将这些信息应用于Hinode太阳能X射线望远镜的现有数据。具体而言，我们使用校准图像进行经典的射旋镜分析以及来自日食的数据，从而对极大的振荡长度具有敏感性。我们证明，与幼稚的计数实验相比，在混合参数方面，利用信号特征可以将约束量增加一个数量级。
The Sun may copiously produce hypothetical light particles such as axions or dark photons, a scenario which can be experimentally probed with so-called helioscopes. Here we investigate the impact of the angular and spectral distribution of solar dark photons on the sensitivity of such instruments. For the first time we evaluate this spectral and angular dependence of the dark photon flux over the whole mass range and apply this information to existing data from the Hinode Solar X-Ray Telescope. Specifically we use calibration images for a classical helioscope analysis as well as data from a solar eclipse providing sensitivity to exceptionally large oscillation lengths. We demonstrate that exploiting the signal features can boost the constraints by more than one order of magnitude in terms of the mixing parameter compared to a naive counting experiment.
