Solar neutrino records: Gauss or non-Gauss is the question

This article discusses the possible variation of the solar neutrino flux over time in the records of Super-Kamiokande-I and the relation to non-equilibrium statistical mechanics and the entropic pathway model. The scaling behavior of the Super-Kamiokande-I time series is investigated utilizing Standard Deviation Analysis and Diffusion Entropy Analysis. The data set exhibit scaling behavior and may follow Levy-type probability distribution function.
