Monte Carlo simulation of an experiment looking for radiative solar neutrino decays

We analyse the possibility of detecting visible photons from a hypothetical radiative decay of solar neutrinos. Our study is focused on the simulation of such measurements during total solar eclipses and it is based on the BP2000 Standard Solar Model and on the most recent experimental information concerning the neutrino properties.Comment: 13 pages, 10 figures, accepted by Astropart.

Search for possible neutrino radiative decays during the 2001 total solar eclipse

We present the results of the observations performed in the occasion of the June 21, 2001 total solar eclipse, looking for visible photons emitted trough a possible radiative decay of solar neutrinos. We establish lower limits for the neutrino proper lifetimes larger than 1000 s/eV, for neutrino masses larger than 0.01 eV.Comment: 18 pages, 11 figures, accepted by Astopart. Phys, updated reference
