| ABSTRACT: |
The models with gauge mediation are quite attractive to realize phenomenologically viable supersymmetric standard model. From the cosmological point of view, the models with the very light gravitino with a mass in the eV range is also motivated since it does not cause any cosmological problems. The models with such a light gravitino mass is, however, known to difficult to be realized. In this talk, I explain our recent models which realize such a very light gravitino mass. I also discuss a separate topic in gauge mediation, the lightest Higgs boson mass in gauge mediation. In the MSSM with gauge mediation, the Higgs boson mass is usually predicted at the lower edge of the experimental bound. We show however, the Higgs boson mass can be much enhanced even if we do not extend the models. |
