摘要：

It has been noted for a long time that, in some circumstances, massless neutrinos may be mired in the leptonic charged current. Conventional neutrino oscillation searches in vacuum are insensitive to this mixing. We discuss the effects of resonant massless-neutrino conversions in the dense medium of a supernova. In particular, we show how the detected <(nu)over bar>(e) energy spectra from SN 1987A and the supernova r-process nucleosynthesis may be used to provide very stringent constraints on the mixing of massless neutrinos.
