Resonant Trispectrum and a Dozen More Primordial N-point functions
  We compute all N-point primordial curvature correlation functions from
inflation at tree-level up to N of order ten or more depending on the choice of
parameters. This is achieved for resonant inflationary models in which the
inflaton potential has a periodic modulation on top of a slow-roll flat term.
These models find a natural UV completion in string theory implementation of
axion monodromy. Key to the success of our computation is the observation that
gravitational interactions among the perturbations can be neglected, which we
argue is justified for any model of inflation with parametrically large
non-Gaussianity. We provide a comprehensive review and detailed derivations of
known consistency relations for squeezed and collinear limits, and generalize
them to any N-point function.
