Query: GUT Scale Inflation, Non-Thermal Leptogenesis, and Atmospheric Neutrino
  Oscillations   Leptogenesis scenarios in supersymmetric hybrid inflation models are
considered. Sufficient lepton asymmetry leading to successful baryogenesis can
be obtained if the reheat temperature T_r>10^6 GeV and the superpotential
coupling parameter kappa is in the range 10^-6<kappa<10^-2. For this range of
kappa the scalar spectral index n_s=0.99+-0.01. Constraints from neutrino
mixing further restrict the range of kappa that is allowed. We analyze in
detail the case where the inflaton predominantly decays into the
next-to-lightest right handed Majorana neutrino taking into account especially
the constraints from atmospheric neutrino oscillations.
