Supersymmetric Inflation, Baryogenesis and ν_μ - ν_τ Oscillations

Abstract

In a supersymmetric left-right symmetric model, inflation, baryogenesis (via leptogenesis) and neutrino oscillations can become closely linked. A familiar ansatz for the neutrino Dirac masses and mixing of the two heaviest families, together with the MSW resolution of the solar neutrino puzzle, imply that 1 eV <_\sim m_{ν_{τ}<_\sim 9 eV. The predicted range for the mixing angle θ_μτwill be partially tested by the Chorus/Nomad experiment. The CP violating phase δ_{μτ} is also discussed.
