Inflection Point Inflation in Supergravity
Manuel Drees, Wenbin Zhao
In this paper, we study the inflection point inflation generated by a polynomial superpotential and a canonical Kähler potential under the supergravity framework, where only one ch…

Parameter Space of Leptogenesis in Polynomial Inflation
Manuel Drees, Yong Xu
Polynomial inflation is a very simple and well motivated scenario. A potential with a concave ``almost'' saddle point at field value fits well the cosmic microwave backgro…
