对Super-Kamiokande 22年太阳$^8$B中微子数据的广义Lomb-Scargle分析
Generalized Lomb-Scargle Analysis of 22 years of Super-Kamiokande solar $^8$B neutrino data
AI总结：
本文用广义Lomb-Scargle周期图分析Super-Kamiokande 22年太阳$^8$B中微子数据，验证此前发现的9.43/年周期信号，结果表明该信号仅为统计涨落，无真实周期性。
摘要：
我们将广义Lomb-Scargle周期图应用于Super-Kamiokande探测到的22年太阳$^{8}$B中微子通量数据。这项工作的主要动机是检验我们曾用前五年Super-K数据发现的、频率为9.43/年（周期为38天）的边缘显著正弦调制是否在累积数据中持续存在。我们使用四种不同的度量来计算显著性。在更新后的数据中，我们未发现上述频率或任何其他频率存在周期性的证据。因此，前五年数据中边缘检测到的9.43/年周期性只是统计涨落。
英文摘要：
We apply the generalized Lomb-Scargle periodogram to 22 years data of solar $^{8}$B neutrino fluxes detected by Super-Kamiokande. The primary motivation of this work was to check if the sinusoidal modulation at a frequency of 9.43/year (with a period of 38 days), which we had found to be marginally significant with the first five years of Super-K data, persists, with the accumulated data. We use four different metrics for the calculation of significance. We do not find any evidence for periodicity at the aforementioned frequency or any other frequency with the updated data. Therefore the marginally detected periodicity at 9.43/year with the first five years of data was only a statistical fluctuation.
