Spin-flavor oscillations and neutrinos from SN 1987A
- Institute of Astronomy, University of Cambridge, Madingley Road, Cambridge CB3 0HA (United Kingdom)
The neutrino signal from SN 1987A is analyzed with respect to spin-flavor oscillations between electron antineutrinos {bar {nu}}{sub e} and muon neutrinos {nu}{sub {mu}} by means of a maximum likelihood analysis. Following Jegerlehner {ital et al.} best fit values for the total energy released in neutrinos, E{sub t}, and the temperature of the electron antineutrino, T{sub {bar {nu}}{sub e}}, for a range of mixing parameters and progenitor models are calculated. In particular the dependence of the inferred quantities on the metallicity of the supernova is investigated and the uncertainties involved in using the neutrino signal to determine the neutrino magnetic moment are pointed out. {copyright} {ital 1997} {ital The American Physical Society}
