担当者:Sergey Ketov "F(R) Supergravity and Early Universe" Abstract: In my talk I propose a new approach to realize a viable chaotic inflation in supergravity, in four spacetime dimensions. The approach is based on the new version (or extension) of supergravity that we call F(R) supergravity. The F(R) supergravity may be understood as the N=1 locally supersymmetric extension of f(R)-gravity theories. In the first part of my talk I briefly review our motivation (Bag Bang, inflation,High-Energy Physics), and recall the basics of inflation. The Starobinsky model of chaotic inflation is considered in detail, as an example. Next, I outline a construction of F(R) supergravity in superspace, and give some of its applications to the early Universe. In particular, I explain how to embed the Starobinsky model of chaotic inflation into the F(R) supergravity. |
