DESCRIPTION:Dr Koushik Dutta (Saha Institute\, Kolkata)\nA generic featur
 e of SUGRA/string models are the existence moduli fields which have Planck
  suppressed couplings to Standard Model fields. The post-inflationary mini
 ma of these fields are generically shifted away from the inflationary mini
 ma\, and as an effect the coherent oscillations of these fields can easily
  dominate ('non-thermal epoch') the energy density of the Universe after u
 sual reheating caused by the inflaton. In this scenario\, we will show how
  inflationary observables are related to the lightest modulus in the theor
 y. In particular\, the predictions for spectral index and tensor-to-scalar
  ratio of any inflation model is highly sensitive to the modulus mass.
