A Black Hole Conjecture and Rare Decays in Theories with Low Scale Gravity
C. Bambi, A. D. Dolgov, K. Freese
In models with large extra dimensions, where the fundamental gravity scale can be in the electroweak range, gravitational effects in particle physics may be noticeable even at rela…
Moduli Inflation with Large Scale Structure Produced by Topological Defects
Katherine Freese, Tony Gherghetta, Hideyuki Umeda
It is tempting to inflate along one of the many flat directions that arise in supersymmetric theories. The required flatness of the potential to obtain sufficient inflation and to…
Calculation of Particle Production by Nambu Goldstone Bosons with Application to Inflation Reheating and Baryogenesis
Alexandre Dolgov, Katherine Freese
A semiclassical calculation of particle production by a scalar field in a potential is performed. We focus on the particular case of production of fermions by a Nambu-Goldstone bos…
A Coupling of Pseudo Nambu Goldstone Bosons to Other Scalars and Role in Double Field Inflation
Katherine Freese
We find a coupling of Pseudo Nambu Goldstone bosons (PNGBs) to other (ordinary) scalars, and consider its importance in various contexts. Our original motivation was the model of D…
The Scalar Field Potential in Inflationary Models: Reconstruction and Further Constraints
Fred C. Adams, Katherine Freese
In this paper, we present quantitative constraints on the scalar field potential for a general class of inflationary models. (1) We first consider the reconstruction of the inflati…
A Possible Solution to the Horizon Problem: The Mad Era for Massless Scalar Theories of Gravity
Janna J Levin, Katherine Freese
Extensions of Einstein gravity which allow the gravitational constant to change with time as the universe evolves may provide a resolution to the horizon problem without invoki…
