BICEP's bispectrum
  The simplest interpretation of the Bicep2 result is that the scalar
primordial power spectrum is slightly suppressed at large scales. These models
result in a large tensor-to-scalar ratio $r$. In this work we show that the
type of inflationary trajectory favoured by Bicep2 also leads to a larger
non-Gaussian signal at large scales, roughly an order of magnitude larger than
a standard slow-roll trajectory.
