Linking the slow-roll scenario and the Dirac–Born–Infeld scenario of ultra-relativistic roll (where, thanks to the warp factor, the inflaton moves slowly even with an ultra-relativistic Lorentz factor), we find that the KKLMMT D3–-brane inflation is robust; that is, enough e-folds of inflation is quite generic in the parameter space of the model. We show that the intermediate regime of relativistic roll can be quite interesting observationally. Introducing appropriate inflationary parameters… 

Cosmology of the tachyon in brane inflation

In certain implementations of the brane inflationary paradigm, the exit from inflation occurs when the branes annihilate through tachyon condensation. We investigate various cosmological effects

Cosmology of the Tachyon in Brane Inflation

In certain implementations of the brane inflationary paradigm, the exit from inflation occurs when the branes annihilate through tachyon condensation. We investigate various cosmological effects

Comparing brane inflation to WMAP

We compare the simplest realistic brane inflationary model to recent cosmological data, including Wilkinson Microwave Anisotropy Probe (WMAP) three-year cosmic microwave background (CMB) results,

Comparing infrared Dirac-Born-Infeld brane inflation to observations

We compare the infrared Dirac-Born-Infeld brane inflation model to observations using a Bayesian analysis. The current data cannot distinguish it from the $\ensuremath{\Lambda}\mathrm{CDM}$ model but

On the slow roll expansion for brane inflation

This note investigates the applicability of the slow roll approximation in inflationary models of this type and derives a slow roll expansion of Liddle, Parsons and Barrow for the case of the DBI action.

A Microscopic Limit on Gravitational Waves from D-brane Inflation

We derive a microscopic bound on the maximal field variation of the inflaton during warped D-brane inflation. By a result of Lyth, this implies an upper limit on the amount of gravitational waves

Inflation from wrapped branes

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 simple

Gravitational wave constraints on Dirac–Born–Infeld inflation

An upper bound on the amplitude of the primordial gravitational wave spectrum generated during ultra-violet Dirac–Born–Infeld (DBI) inflation is derived. The bound is insensitive to the form of the

Constraining Inflationary Scenarios with Braneworld Models and Second Order Cosmological Perturbations

Inflationary cosmology is the leading explanation of the very early universe. Many different models of inflation have been constructed which fit current observational data. In this work theoretical

Dirac–Born–Infeld inflation using a one-parameter family of throat geometries

We demonstrate the possibility of examining cosmological signatures in the Dirac–Born–Infeld (DBI) inflation setup using the BGMPZ solution, a one-parameter family of geometries for the warped throat

Brane inflation and cosmic string tension in superstring theory

In a simple reanalysis of the KKLMMT scenario, we argue that the slow roll condition in the -brane inflationary scenario in superstring theory requires no more than a moderate tuning. The cosmic

Brane Inflation

The Inflationary Brane-Antibrane Universe

We show how the motion through the extra dimensions of a gas of branes and antibranes can, under certain circumstances, produce an era of inflation as seen by observers trapped on a 3-brane, with the

Brane interaction as the origin of inflation

We reanalyze brane inflation with brane-brane interactions at an angle, which include the special case of brane-anti-brane interaction. If nature is described by a stringy realization of the brane

On the Moduli Dependence of Nonperturbative Superpotentials in Brane Inflation

We discuss string corrections to the effective potential in various models of brane inflation. These corrections contribute to the mass of the inflaton candidate and may improve its slow-roll

Multithroat brane inflation

We present a scenario where brane inflation arises more generically. We start with D3 and anti-D3-branes at the infrared ends of two different throats. This setup is a natural consequence of the
