Non-Gaussianities in a two-field generalization of Natural Inflation
  We describe a two-field model that generalizes Natural Inflation, in which
the inflaton is the pseudo-Goldstone boson of an approximate symmetry that is
spontaneously broken, and the radial mode is dynamical. We analyze how the
dynamics fundamentally depends on the mass of the radial mode and
calculate/estimate the non-Gaussianities arising from such a scenario.
