过冲问题与巨结构

The Overshoot Problem and Giant Structures

Nissan Itzhaki

摘要:

小场暴胀模型经常受到过冲问题的困扰。最近在弦论的背景下,有人提出了一个特别有效的解决方案。我们表明,该决议预测存在的巨型球对称过密区域的半径至少为110兆秒差距。我们认为,如果这种结构将被发现,他们可以提供一个实验窗口到弦论。

英文摘要:

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.
