| dc.description | The nonsupersymmetric as well as the supersymmetric hybrid inflationary model is reviewed. The scenario of baryogenesis via a primordial leptogenesis is discussed and the role of the nonperturbative electroweak sphaleron effects is analyzed. A supersymmetric model based on a left-right symmetric gauge group, which `naturally' leads to hybrid inflation, is presented. The mu problem is solved, in this model, and the baryon asymmetry of the universe is produced through leptogenesis. For masses of nu_mu, nu_tau from the small angle MSW resolution of the solar neutrino problem and SuperKamiokande, maximal nu_mu-nu_tau mixing can be achieved. The required values of the relevant parameters are, however, quite small. | |
