Query: A search for evidence of solar rotation in Super-Kamiokande solar
  neutrino dataset   We apply the generalized Lomb-Scargle (LS) periodogram, proposed by
Zechmeister and Kurster, to the solar neutrino data from Super-Kamiokande
(Super-K) using data from its first five years. For each peak in the LS
periodogram, we evaluate the statistical significance in two different ways.
The first method involves calculating the False Alarm Probability (FAP) using
non-parametric bootstrap resampling, and the second method is by calculating
the difference in Bayesian Information Criterion (BIC) between the null
hypothesis, viz. the data contains only noise, compared to the hypothesis that
the data contains a peak at a given frequency. Using these methods, we scan the
frequency range between 7-14 cycles per year to look for any peaks caused by
solar rotation, since this is the proposed explanation for the statistically
significant peaks found by Sturrock and collaborators in the Super-K dataset.
From our analysis, we do confirm that similar to Sturrock et al, the maximum
peak occurs at a frequency of 9.42/year, corresponding to a period of 38.75
days. The FAP for this peak is about 1.5% and the difference in BIC (between
pure white noise and this peak) is about 4.8. We note that the significance
depends on the frequency band used to search for peaks and hence it is
important to use a search band appropriate for solar rotation. However, the
significance of this peak based on the value of BIC is marginal and more data
is needed to confirm if the peak persists and is real.
