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…
Probing CP-violation at colliders through interference effects in diboson production and decay
Jason Kumar, Arvind Rajaraman, James D. Wells
We define a CP-asymmetric observable that is sensitive to CP-violating interactions in the gauge-boson sector. We illustrate the utility of this observable by studying how well the…
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…
Probing the Green-Schwarz Mechanism at the Large Hadron Collider
Jason Kumar, Arvind Rajaraman, James D. Wells
We investigate the phenomenology of new abelian gauge bosons, which we denote as bosons, that suffer a mixed anomaly with the Standard Model, but are made self-consistent by th…
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…
