Summary
Two upper limits for the depth of the degenerate (anti) neutrino sea are discussed. The first one is based on a recent experimental upper limit for the density of antineutrinos with energy between 400 MeV and 12 MeV. The second makes use of the energy dependence of the observed K2→2π events.
Riassunto
Si discutono due limiti superiori della profondità del mare di (anti) neutrini degenerato. Il primo si basa su un recente limite superiore sperimentale della densità degli antineutrini aventi energia fra 400 MeV e 12 MeV. Il secondo fa uso della dipendenza dall’energia degli eventi K2→2π osservati.
