标题： Monodromy Inflation in SUSY QCD

摘要： BICEP2 实验发现了一个较大的张量-标量比，这表明了暴胀期间存在大的场漂移。预测较大$r$的一个框架是单值性暴胀。虽然它主要在弦理论背景下讨论，但这种现象可以在对具有大量颜色的超对称 QCD 的良好理解框架中被阐释和研究。我们讨论了可行暴胀的要求以及模型构建中的各种困难，包括隧道效应、微调问题和物种问题。 显示英文摘要

摘要： The discovery of a large tensor-to-scalar ratio by the BICEP2 experiment points to large field excursions during inflation. One framework that predicts large $r$ is monodromy inflation. While discussed mainly in the context of string theory, the phenomenon can be illustrated and studied in the well-understood framework of SUSY QCD with a large number of colors. We discuss the requirements for viable inflation as well as various difficulties for model building, including tunneling, tuning, and the species problem.
