Inflationary tails, and other multi-field stories
Motivated by primordial black holes as a dark matter candidate, I will discuss some interesting properties of the primordial curvature perturbations generated during multi-field inflation. Among them: power spectrum features, non-gaussianity —or otherwise— of small perturbations, and the statistics of large, rare, curvature fluctuations (“non-gaussian tails”).
