Abstract
We propose a supersymmetric model with a left-right symmetric gauge gr oup where hybrid inflation,baryogenesis and neutrino oscillations are closely linked. This scheme, supplemented by a familiar ansatz for the neutrino Dirac masses and mixing of the two heaviest families and wit h the MSW resolution of the solar neutrino puzzle, implies that 1 eV l ess than or similar to m(nu tau) less than or similar to 9 eV. The mix ing angle 8,1 is predicted to lie in a relatively narrow range which w ill be partially reared by the Chorus/Nomad experiment. Restrictions o n the CP violating phase delta(mu tau) are also derived (C) 1998 Elsev ier Science B,V. All rights reserved.
