"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.
