Statistic analysis of neutrino events from the burst SN1987A in Cherenkov detectors: evaluation of the electron antineutrino mass.

The method of the statistic sample moments was used for analysis of the neutrino events from the burst SN1987A in Cherenkov detectors. Comparison of the analysis results with the predictions of the current model of stellar-core collapse allows to evaluate the electron antineutrino mass as 20+9 eV/c^2.
