CMBPol Mission Concept Study: Probing Inflation with CMB Polarization

Daniel Baumann, Mark G. Jackson, Peter Adshead +56

We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…

Fine-Tuning in DBI Inflationary Mechanism

Xingang Chen

We show a model-independent fine-tuning issue in the DBI inflationary mechanism. DBI inflation requires a warp factor h small enough to sufficiently slow down the inflaton. On the…

Generation and Characterization of Large Non-Gaussianities in Single Field Inflation

Xingang Chen, Richard Easther, Eugene A. Lim

Inflation driven by a single, minimally coupled, slowly rolling field generically yields a negligible primordial non-Gaussianity. We discuss two distinct mechanisms by which a non-…
