A Search for Periodicity in the Super-Kamiokande Solar Neutrino Flux Data

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.
