Abstract

I describe the first model of chaotic inflation in supergravity, which was proposed by Goncharov and the present author in 1983. The inflaton potential of this model has a plateau-type behavior V0(183e6ϕ)V_{0} (1- {8\over 3}\, e^{-\sqrt 6 |\phi|}) at large values of the inflaton field. This model predicts ns=12N0.967n_{s} = 1-{2\over N} \approx 0.967 and r=43N24×104r = {4\over 3 N^{2}} \approx 4 \times 10^{{-4}}, in good agreement with the Planck data. I propose a slight generalization of this model, which allows to describe not only inflation but also dark energy and supersymmetry breaking.
