Galileon Inflation and Non-Gaussianities – Andrew Tolley

I will discuss a new class of inflationary models based upon the idea of Galileon fields, scalar fields that exhibit non-linearly realized symmetries. These models predict distinctive non-Gaussian features in the primordial power spectrum, and I will discuss how they relate with, and can be distinguished from, canonical inflation, k-inflation, ghost inflation, and DBI-inflationary models.
