Abstract

We show that the late-decaying particle scenario may be realized in the supersymmetric singlet majoron model with the majoron scale 10-200 TeV. The smajoron decaying into two neutrinos is the late-decaying particle with the mass 0.1-1 TeV and the life-time 2×103-8×104 seconds. The lower limit of the majorino mass is 4-40 TeV in order to avoid the overclosure of the universe due to the decay-produced LSP. The muon neutrino and the tau neutrino can be used to explain the atmospheric and the solar neutrino deficit.
