Baryogenesis and Gravitino Dark Matter in Gauge-Mediated Supersymmetry-Breaking Models
We discuss two cosmological issues in a generic gauge-mediated supersymmetry (SUSY)-breaking model, namely the Universe's baryon asymmetry and the gravitino dark-matter density. We show that both problems can be simultaneously solved if there exist extra matter multiplets of a SUSY-invariant ma...
