Scientific paper

Fermions trapped inside a closed domain wall may cool to degeneracy and form a long-lived structure. In the context of spontaneous left-right-symmetry breaking, we show that trapped right-handed neutrinos cool due to annihilations to electron-positron pairs if the initial temperature is less than 0.21me. The surface tension of the wall must be less than (1.93 TeV)3. The lifetime of the neutrino ball (NB) is determined by neutrino annihilation to three photons and may be comparable to the age of the Universe. These NB's are in the 104-107 solar mass range and radiate γ rays in the few hundred keV range at a rate of 1040-1044 erg/sec range. NB's die in a 1056-1059 erg electron-positron burst.
