Simple Bounds from the Perturbative Regime of Inflation
Louis Leblond, Sarah Shandera
We examine the conditions under which a perturbative expansion around an inflating background is valid. When inflation is driven by a single field with a general sound speed, we fi…
Inflation from Wrapped Branes
Melanie Becker, Louis Leblond, Sarah Shandera
We show that the use of higher dimensional wrapped branes can significantly extend the inflaton field range compared to brane inflation models which use D3-branes. We construct a s…
Slow Roll in Brane Inflation
Sarah E. Shandera
We address the issue of slow-roll in string theory models of inflation. Using a Kähler transformation and results from the D3-D7 model, we show why we expect flat directions to be…
Inter-brane Interactions in Compact Spaces and Brane Inflation
Sarah Shandera, Benjamin Shlaer, Horace Stoica +1
It was pointed out that brane-anti-brane inflation without warped geometry is not viable due to compactification effects (in the simplified scenario where the inflaton is decoupled…
