| Research Abstract |
1. We showed that the neutrino mass suggested by MSW solution to the solar neutrino problem is consistent with the SUSY-GUT's.
2. We showed that the decay of the heavy right-handed neutrino produces the baryon asymmetry in the universe.
3. We constructed a supergravity model where the scalar partner of the right-handed neutrino can be an inflation for the chaotic inflation.
4. We found that the polonyi problem can be solved in the no-scale type supergravity.
5. We proposed a new unified model in where the light Higgs doublets are naturally generated.
6. We found a new dynamical model for the SUSY breaking. We showed that there is no Poloxyi problem in this model.
