Inflection point in running kinetic term inflation

Abstract

In this work, we consider inflection point inflation in the framework of running kinetic term inflation in supergravity. 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 $1\sigma$ confidence region allowed by the result of Planck 2015.
