Comparison of neutrino mass limits from tritium decay and supernova data.

Discussion on interpretation issues related to neutrino mass.

Abstract

The definition method of the limit for the neutrino mass of rest by using the analysis of the extreme values of the beta-particles distribution under beta-decay is given. The anomaly of distribution at the end of the curve was analyzed. The results of the experiments by spectrum analysis of electrons under tritium disintegration and the results recording of the stream of neutrinos from the supernova SN-1987A flash to estimate the limit for the neutrino mass were analyzed and compared. The problems of interpretation of the results obtained disappear in the case the mass less flavor of neutrino along with mass neutrino.
