- Title
Search for Neutrino Radiative Decay with a Prototype Borexino Detector.
- Authors
Derbin, A. V.; Smirnov, O. Ju.
- Abstract
Results of background measurements with a prototype of the Borexino detector were used to obtain bounds on the lifetime of radiative neutrino decay ν[sub H] → ν[sub L] + γ. The new lower limit for the lifetime of pp and [sup 7]Be neutrinos is τ[sub c.m.](ν[sub H] → ν[sub L] + γ)/m[sub ν] ≥ 4.2 × 10[sup 3] s eV[sup –1] (α = 0). It is more than an order of magnitude stronger than the value obtained in previous experiments using nuclear reactors and accelerators. © 2002 MAIK “Nauka / Interperiodica”.
