Large Field Inflation Models from Higher-Dimensional Gauge Theories

Understand

Motivated by the recent detection of B-mode polarization of CMB by BICEP2 which is possibly of primordial origin, we study large field inflation models which can be obtained from higher-dimensional gauge theories.

• The constraints from CMB observations on the gauge theory parameters are given, and their naturalness are discussed.
• Among the models analyzed, Dante's Inferno model turns out to be the most preferred model in this framework.
