Structure formation with majoron supermultiplet

Technical Report:

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 majoron decaying into two neutrinos is the late-decaying particle with the mass 0.1 - 1 TeV and the life-time 2 X 10{sup 3} - 8 X 10{sup 4} 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. (author). 18 refs, 2 tabs.
