AI总结：
暗SRF实验通过改进的理论建模提升了高频不稳定性的分析，得出比之前强一个数量级的暗光子排除界，对应信号噪声比高四数量级，为非暗物质暗光子在6μeV以下质量范围内的最严格限制。
摘要：
我们报告了来自暗SRF路径探测运行的改进的暗光子排除界限。我们的新结果由高精度共振实验中频率不稳定性改进的理论建模驱动。我们的分析得出一个约束，其强度比之前报告的强一个数量级（对应信号噪声比大四数量级）。该结果代表了在6μeV以下质量范围内的非暗物质暗光子的最严格限制，并转化为对光子质量的最佳实验室限制m_γ<2.9×10^{-48}g。
英文摘要：
We report the refined dark-photon exclusion bound from Dark SRF's pathfinder run. Our new result is driven by improved theoretical modeling of frequency instability in high-quality resonant experiments. Our analysis leads to a constraint that is an order of magnitude stronger than previously reported (corresponding to a signal-to-noise ratio that is four orders of magnitude larger). This result represents the world-leading constraint on non-dark-matter dark photons over a wide range of masses below $6\,\rm μeV$ and translates to the best laboratory-based limit on the photon mass $m_γ<2.9\times 10^{-48}\,\rm g$.
