Query: A model for fluctuating inflaton coupling: (s)neutrino induced adiabatic
  perturbations and non-thermal leptogenesis   We discuss an unique possibility of generating adiabatic density
perturbations and leptogenesis from the spatial fluctuations of the inflaton
decay rate. The key assumption is that the initial isocurvature perturbations
are created in the right handed sneutrino sector during inflation which is then
converted into adiabatic perturbations when the inflaton decays. We discuss
distinct imprints on the cosmic micro wave background radiation, which can
distinguish non-thermal versus thermal leptogenesis.
