弯曲喉道中缠绕DBI膨胀的约束条件
Constraints on Wrapped DBI Inflation in a Warped Throat
摘要：
我们推导出的张量标量比的约束和弯曲的喉DBI膨胀驱动的D5-和D 7-膜包裹在循环的喉的背景电荷。结果表明，背景电荷远远超过已知的最大值是需要在大多数情况下的DBI膨胀产生宇宙学观测值兼容的WMAP 3数据。本文的结果对暴胀子势的细节不敏感，可以应用于一般的弯曲喉道。
英文摘要：
We derive constraints on the tensor to scalar ratio and on the background charge of the warped throat for DBI inflation driven by D5- and D7-branes wrapped over cycles of the throat. It is shown that the background charge well beyond the known maximal value is required in most cases for DBI inflation to generate cosmological observables compatible with the WMAP3 data. Most of the results derived in this paper are insensitive to the details of the inflaton potential, and could be applied to generic warped throats.
