TL;DR
This study searches for periodic patterns in Super-Kamiokande solar neutrino data, finding a notable 13.75-day cycle, and discusses methods to verify and understand this potential periodicity.
Contribution
It introduces a periodogram analysis of Super-Kamiokande data revealing a possible 13.75-day periodicity not previously documented.
Findings
Detected a peak at 13.75 days with 98.9% confidence level
Suggests potential periodic modulation in solar neutrino flux
Provides a basis for further investigation of solar neutrino variability
Abstract
The publicly available Super-Kamiokande 10 day plot data have been searched for a periodic modulation in the range between 10 and 500 days, with the periodogram method. A peak is observed for T = 13.75 days, significant at 98.9% C.L. I discuss possible ways to check this result and, if confirmed, to investigate its origin.
