Inflation from Warped Space
A long period of inflation can be triggered when the inflaton is held up on the top of a steep potential by the infrared end of a warped space. We first study the field theory description of such a model. We then embed it in the flux stabilized string compactification. Some special effects in the throat reheating process by relativistic branes are discussed. We put all these ingredients into a ...
متن کاملInflation in warped geometries
We argue that brane anti-brane inflation in string theory de-Sitter vacua of KachruKallosh-Linde-Trivedi (KKLT) is captured by the dynamics of a D3-brane probe in the local KKLT model constructed in hep-th/0203041. This provides a framework to study in a controllable way corrections to the inflationary slow roll parameter η due to conformal symmetry breaking in a warped geometry throat. We comp...
متن کاملWarped Wilson Line DBI Inflation
We propose a novel inflationary scenario in string theory in which the inflaton field is aWilson line degree of freedom in the worldvolume of a probe Dp-brane, in a warped flux compactification. Kinetic terms for Wilson line fields on the world volume of a D-brane take a nonstandard DiracBorn-Infeld (DBI) form. Thus, we work in the framework of DBI inflation. This extends the original slow roll...
متن کاملWarped Reheating in Brane-Antibrane Inflation
We examine how reheating occurs after brane-antibrane inflation in warped geometries, such as those which have recently been considered for Type IIB string vacua. We adopt the standard picture that the energy released by brane annihilation is dominantly dumped into massive bulk (closed-string) modes which eventually cascade down into massless particles, but argue that the this need not mean tha...
متن کاملWarped Reheating in Multi-Throat Brane Inflation
We investigate in some quantitative details the viability of reheating in multi-throat brane inflationary scenarios by estimating and comparing the time scales for the various processes involved. We also calculate within perturbative string theory the decay rate of excited closed strings into KK modes and compare with that of their decay into gravitons; we find that in the inflationary throat t...
