Description
We show that models of `just enough' inflation, where the slow-roll evolution lasted only 50−60 e-foldings, feature modifications of the CMB power spectrum at large angular scales. We perform a systematic and model-independent analysis of any possible non-slow-roll background evolution prior to the final stage of slow-roll inflation, We find a high degree of degeneracy since all possible backgrounds give rise to just two distinct classes of primordial spectra.
