General inflaton potentials in supergravity
Renata Kallosh, Andrei Linde, Tomas Rube
We describe a way to construct supergravity models with an arbitrary inflaton potential V (ϕ) and show that all other scalar fields in this class of models can be stabilized at the…
New models of chaotic inflation in supergravity
Renata Kallosh, Andrei Linde
We introduce a new class of models of chaotic inflation inspired by the superconformal approach to supergravity. This class of models allows a functional freedom of choice of the i…
The Ultraviolet Finiteness of N=8 Supergravity
Renata Kallosh
We study counterterms (CT's), candidates for UV divergences in the four-dimensional N=8 supergravity. They have been constructed long ago in a Lorentz covariant on shell superspace…
Superconformal Symmetry, NMSSM, and Inflation
Sergio Ferrara, Renata Kallosh, Andrei Linde +2
We identify a particularly simple class of supergravity models describing superconformal coupling of matter to supergravity. In these models, which we call the canonical superconfo…
Light-by-Light Scattering Effect in Light-Cone Supergraphs
Renata Kallosh, Pierre Ramond
We give a relatively simple explanation of the light-cone supergraph prediction for the UV properties of the maximally supersymmetric theories. It is based on the existence of a dy…
New N=4 SYM Path Integral
Chih-Hao Fu, Renata Kallosh
Using Lorentz covariant spinor helicity formalism we reorganize the unitary scalar superfield light-cone path integral for the N=4 supersymmetric Yang-Mills theory. In new variable…
