WMAP9和暴胀的单场模型

WMAP9 and the single field models of inflation

Laila Alabidi

摘要:

使用WMAP的最新版本,我发现对于合理数量的e折叠,自耦合幂p=3的树级势现在被排除在2-sigma区域之外,幂alpha=2/3的轴子单值模型现在被排除在N=47 e折叠和N=61的1-sigma置信区域之外。α =2/5也被排除在N=61的2-sigma区域之外。我还发现,由于运行的上限已经减少,一个显着丰富的PBH需要分数功率的自耦合在山顶型模型。

英文摘要:

Using the latest release from WMAP, I find that for a reasonable number of e-folds the tree-level potential with self coupling power p=3 is now excluded from the 2-sigma region, the axion monodromy model with the power alpha=2/3 is now excluded from the 1-sigma confidence region for N=47 e-folds and for N=61. alpha=2/5 is also excluded from the 2-sigma region for N=61. I also find that since the upper bound on the running has been reduced, a significant abundance of PBHs requires fractional powers of self-coupling in the Hilltop-type model.
