Simple supergravity model of inflation constrained with Planck 2018 data

We study a model of inflation based on N=1 supergravity essentially depending on one effective parameter. Under a field transformation we show that this model turns out to be equivalent to a previously studied supergravity model known to be ruled out with the original choice of the parameter. Such p...
