Search for radiative decays of solar neutrinos during a solar eclipse

TL;DR

This study investigates the potential radiative decays of solar neutrinos by analyzing images captured during total solar eclipses, aiming to detect visible photons emitted from neutrino decays.

Contribution

It presents observational results from two solar eclipses and explores the feasibility of detecting neutrino radiative decays during such events.

Findings

No definitive evidence of neutrino radiative decays was observed.

The analysis sets upper limits on the decay rate of solar neutrinos.

The methodology demonstrates the potential of eclipse observations for neutrino physics.

Abstract

A search for possible radiative decays of solar neutrinos with emission of photons in the visible range may be performed during total solar eclipses. We discuss some results obtained from the digitized images recorded during the August 11, 1999 total solar eclipse in Romania, and report on the observations made in June 21, 2001, in Zambia.
