Does the first chaotic inflation model in supergravity provide the best fit to the Planck data?

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 $V_{0} (1- {8\over 3}, e^{-\sqrt 6 |\phi|})$atlargevaluesoftheinflatonfield\mathrm{.}Thismodelpredicts$n_{s} = 1-{2\over N} \approx 0.967$and$r = {4\over 3 N^{2}} \approx 4 \times 10^{{-4}}$, 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.
