Correlated primordial spectra in effective theory of inflation
  We derive a direct correlation between the power spectrum and bispectrum of
the primordial curvature perturbation in terms of the Goldstone mode based on
the effective field theory approach to inflation. We show examples of
correlated bispectra for the parametrized feature models presented by the
Planck collaboration. We also discuss the consistency relation and the validity
of our explicit correlation between the power spectrum and bispectrum.
