Lower limits on the lifetime of massive neutrino radiative decay from the 2006 total solar eclipse
Institute for Space Sciences, R-77125, Bucharest – MÄgurele, Romania
Abstract. We report on the search for signatures of possible neutrino radiative decays, in occasion of the 2006 total solar eclipse (TSE). The lower lifetime limits obtained in the hypothesis of normal mass hierarchy (m3 >> m 2 > m1) are about 3 orders of magnitude better than the previous results. The inverted mass hierarchy scenario (m2 > m1 >> m3) is also investigated. The reached sensitivity suggests that the limits presented here are the best obtainable using this technique.
