Mezzacappa (Oak Ridge National Laboratory | | Abstract: | Early black hole formation in a core-collapse supernova will abruptly truncate the neutrino fluxes. The sharp cutoff can be used to make model-independent time-of-flight neutrino mass tests. Assuming a neutrino luminosity of $10^{52}$ erg/s per flavor at cutoff and a distance of 10 kpc, SuperKamiokande can detect an electron neutrino mass as small as 1.8 eV, and the proposed OMNIS detector can detect mu and tau neutrino masses as small as 6 eV. This {it Letter} presents the first technique with direct sensitivity to eV-scale mu and tau neutrino masses. | | Source: | arXiv, hep-ph/0006015 | | Services: | Forum | Review | PDF | Favorites | |
