Neutronization neutrino pulses from supernovae and the triplet majoron model
1988
Physics Letters B
Preserved Fulltext
We address a possible implication of the triplet majoron (TM) model for neutrino pulses from supernovae. If the v~v~-majoron coupling is ~ 0.7 X 10-3, suggested by one of the recent ~13-decay experiments, equilibration of v-species via v~v~--.%v,(v~v~), occurs on a time scale ~ 10 -4 s. Rapid equilibration followed by decay in flight via v(v~) --.9~ +X °, could dramatically enhance the probability of observing neutronization neutrinos, even for g~ ~ ~ 10-is. This effect would make nearby supernovae sensitive tests of TM models.
