A Weekly Pattern from Hourly Estimates of the Super-Kamiokande-I Neutrino Flux 1996-2001

TL;DR

This study analyzed hourly neutrino flux data from Super-Kamiokande-I over several years and found a significant weekly pattern, with notably lower neutrino flux on weekends, especially Saturday.

Contribution

It introduces a novel analysis of weekly patterns in neutrino flux data, revealing a significant weekend-weekday difference in neutrino detection rates.

Findings

Significant weekly variation in neutrino flux (p << 0.001)

Lower neutrino flux observed on weekends, especially Saturday

Neutrino flux exhibits a weekly pattern

Abstract

A search for a neutrino flux difference between weekdays and weekend days, for the average week of the Super-Kamiokande-I (SK-I) Experiment, was undertaken using the 5-day period version of the SK-I data taken from May 31st, 1996 to July 15th, 2001. A significant (p << 0.001) difference was found and the most obvious neutrino flux change from weekdays to weekend days can be summarized as follows: "Some neutrinos took the weekend off, especially on Saturday".
