The Overshoot Problem and Giant Structures

High Energy Physics - Theory 2011-08-03 v3 Astrophysics

Abstract

Models of small-field inflation often suffer from the overshoot problem. A particularly efficient resolution to the problem was proposed recently in the context of string theory. We show that this resolution predicts the existence of giant spherically symmetric overdense regions with radius of at least 110 Mpc. We argue that if such structures will be found they could offer an experimental window into string theory.
