Inflection point in running kinetic term inflation

Year: 2017

Type: article

Abstract: In this work, we calculate the general form of the scalar potential with polynomial superpotential in the framework of running kinetic term inflation, then focus on a polynomial superpotential with two terms and obtain the inflection point inflationary model. We study the inflationary dynamics and show that the predicted value of the scalar spectral index and tensor-to-scalar ratio can lie within the [Formula: see text] confidence region allowed by the result of Planck 2015.
