New Lower Limits on the Lifetime of Heavy Neutrino Radiative Decay
The data collected during the 2006 total solar eclipse are analyzed in the search for signals produced by a hypothetical radiative decay of massive neutrinos. In the absence of the expected light pattern, we set lower limits for the massive neutrino components proper lifetime. The reached sensitivity indicates thet these are the best limits obtainable with this method.
