超级山顶通货膨胀

Super Hilltop Inflation

Chia-Min Lin, Kingman Cheung

摘要:

本文考虑了超对称山顶F项和D项混合暴胀模型的对数辐射修正和高阶项。传统的F项和D项混合通货膨胀仅预测$n_s \gae 0.98$。我们发现,通过正二次和负四次修正,谱指数可以约化为最新WMAP结果所建议的$n_s=0.96$,如果F项暴胀用$κ\lae 0.01$,D项暴胀用$g \lae 0.05$,那么通过适当调整参数,可以解决SUSY混合暴胀中出现的宇宙弦问题.

英文摘要:

In this paper, we consider logarithmic radiative corrections and higher order terms to the supersymmetric hilltop F- and D-term hybrid inflation models. Conventional F- and D-term hybrid inflation only predicts $n_s \gae 0.98$. We show that via a positive quadratic and a negative quartic correction the spectral index can be reduced to $n_s=0.96$ suggested from latest WMAP result and also cosmic string problem appeared in SUSY hybrid inflation can be solved with mild tuning of the parameters if $κ\lae 0.01$ for F-term inflation and $g \lae 0.05$ for D-term inflation.
