INFORMATION ON NEUTRINO MASSES OBTAINED FROM SUPERNOVA 1987a DATA
-
Abstract
Under the assumption that all the neutrino events in the observation of KAMIOKANDE-11 detector on February 23, 1987, may be produced from one short neutrino burst in the Supernova 1987a within a few tenths of second, these neutrino events can be divided into three groups with neutrino masses 4.15eV. 18.7eV and 28.5eV, respectively.
