The Inflationary Trispectrum for Models with Large Non-Gaussianities
Xingang Chen, Min-xin Huang, Gary Shiu
We compute the leading order contribution to the four-point function of the primordial curvature perturbation in a class of single field models where the inflationary Lagrangian is…
Is Brane Inflation Eternal?
Xingang Chen, Sash Sarangi, S. -H. Henry Tye +1
In this paper, we show that eternal inflation of the random walk type is generically absent in the brane inflationary scenario. Depending on how the brane inflationary universe ori…
Observational Signatures and Non-Gaussianities of General Single Field Inflation
Xingang Chen, Min-xin Huang, Shamit Kachru +1
We perform a general study of primordial scalar non-Gaussianities in single field inflationary models in Einstein gravity. We consider models where the inflaton Lagrangian is an ar…
Heating in Brane Inflation and Hidden Dark Matter
Xingang Chen, S. -H. Henry Tye
Towards the end of brane inflation, the brane pair annihilation produces massive closed strings. The transfer of this energy to Standard Model (SM) open string modes depends on whe…
