Neutrino Oscillations in Neutron Star Matter
Abstract
We discuss the hypothesis suggested by Mazurek (1979) that neutrino oscillations (v e ⇄v μ) could transfer leptonic zero-point energy (e -,v e ; γ<4/3) to baryons during the gravitational collapse of a massive star (M≳10M ⊙) and that subsequently the collapse ends in a stellar explosion (γ>4/3). The estimation of the lengths of neutrino oscillations if occuring in vacuum or dense matter, respectively, shows, however, that vacuum oscillations can be suppressed in dense matter and, therefore, should have no influence on the neutrino emission of neutron stars.
