Heavy Tau Neutrino as the Late Decaying Particle in the Cold Dark Matter Scenario

Abstract

The tau neutrino with a mass of about 10 MeV can be the ``late decaying particle'' in the cold dark matter scenario for the formation of structure in the Universe. We show how this may be realized specifically in the recently proposed doublet Majoron model.
