Sterile neutrinos and supernova nucleosynthesis
Sterile neutrinos and supernova nucleosynthesis
A light sterile neutrino species has been introduced to explain simultaneously the solar and atmospheric neutrino puzzles and the results of the LSND experiment, while providing for a hot component of dark matter. Employing this scheme of neutrino masses and mixings, we show how matter-enhanced active-sterile $({\ensuremath{\nu}}_{\ensuremath{\mu},\ensuremath{\tau}}\ensuremath{\rightleftharpoons}{\ensuremath{\nu}}_{s})$ neutrino transformation followed …
