Extended D-term Hybrid Inflation

چکیده

In this paper, we show that if we extend D-term hybrid inflation by adding a light scalar field which couples to a waterfall field, large non-Gaussianity can be generated at the end of inflation. Contribution of cosmic strings generated after D-term inflation to the Cosmic Microwave Background (CMB) angular power spectrum can be as low as 10% and this also evade the spectral index problem.

Super Hilltop Inflation

In this paper, we consider logarithmic radiative corrections and higher order terms to the supersymmetric hilltop Fand D-term hybrid inflation models. Conventional Fand D-term hybrid inflation only predicts ns > ∼ 0.98. We show that via a positive quadratic and a negative quartic correction the spectral index can be reduced to ns = 0.96 suggested from latest WMAP result and also cosmic string p...

We consider hybrid inflation in the braneworld scenario. In particular, we consider inflation in global supersymmetry with the D-terms in the scalar potential for the inflaton field to be the dominant ones (D-term inflation). We find that D-term dominated inflation can naturally accomodate all requirements of the successful hybrid inflationary model also in the framework of D-brane cos-mology w...

F-term, D-term and hybrid brane inflation

We study inflation and reheating in models for the brane universe, considering hybrid brane inflation without tachyon condensation. We expect that some fields that are localized on different branes interact with O(1) coupling when branes are on top of each other, while the interaction vanishes when branes are separated at a distance. If the interaction is needed to avoid spontaneous breaking of...
