Phenomenological analysis of neutrino emission from SN 1987A.
Abstract
The allowed range of the nu(e) emission temperature, rise time, cooling time, flux, and total energy of the neutrino emission from SN 1987A are determined from Monte Carlo and maximum likelihood analyses. The acceptable ranges are found to be 4.2 + 1.2, - 0.8 MeV for temperature, 4.5 + 1.7, - 2.0 sec for cooling time, and 6.1 + 3.5, - 3.6 x 10 to the 52nd N(all) erg for total emitted energy, where N(all) is the ratio of energy emitted in all neutrino forms to that emitted in the form of nu(e). It is suggested that masses of nu(e) that exceed 16 eV at the 5 percent significance level can be rejected.
