摘要：

A detailed investigation of hybrid inflation and the subsequent reheating process is performed within a mu-problem solving supersymmetric model based on a left-right symmetric gauge group. The process of baryogenesis via leptogenesis is especially studied. For nu(mu), nu(tau) masses from the small angle MSW resolution of the solar neutrino problem and the recent results of the SuperKamiokande experiment, we show that maximal nu(mu)-nu(tau) mixing can be achieved. The required Value of the relevant coupling constant is, however, quite small (similar to 10(-6)). (C) 1998 Elsevier Science B.V. All rights reserved.
