Tachyon Mediated Non-Gaussianity
Bhaskar Dutta, Jason Kumar, Louis Leblond
We describe a general scenario where primordial non-Gaussian curvature perturbations are generated in models with extra scalar fields. The extra scalars communicate to the inflaton…
Intersecting Brane Models and Cosmology
Jason Kumar
We discuss the application of general features of intersecting brane model constructions in cosmology. In particular, we describe a scenario for D-term inflation which arises strai…
Dynamical SUSY Breaking in Intersecting Brane Models
Jason Kumar
We present a simple mechanism by which supersymmetry can be dynamically broken in intersecting brane models, naturally generating an exponentially small scale. Rather than utilize…
An Inflationary Scenario in Intersecting Brane Models
Bhaskar Dutta, Jason Kumar, Louis Leblond
We propose a new scenario for D-term inflation which appears quite straightforwardly in the open string sector of intersecting brane models. We take the inflaton to be a chiral fie…
