Power Suppression in D-Brane Inflation
Abstract
Cosmological inflation is the period of rapid, accelerated expansion that occurred in the fraction of a second between the creation of spacetime and the Big Bang. Its proposal 35 years ago singlehandedly solved the three greatest issues of the Big Bang model . Now, researchers have found that certain inflation models may solve one more puzzle: the anomalous power-suppression at large angles in the cosmic microwave background (CMB). Despite consensus to the contrary, we argue that D-brane inflation is one such model. We show that there are initial conditions for which inflation deviates from “slow-roll inflation” dramatically enough to show adequate power-suppression in the CMB.
