Effects of degenerate sterile neutrinos on the supernova neutrino flux
arXiv:hep-ph/0401082 · doi:10.1016/j.physletb.2004.07.041
Abstract
We consider the possibility that there exist sterile neutrinos which are closely degenerate in mass with the active neutrinos and mixed with them. We investigate the effects of this kind of active-sterile neutrino mixing on the composition of supernova neutrino flux at the Earth. If an adiabatic MSW-transition between active and sterile neutrinos takes place, it could dramatically diminish the electron neutrino flux.
