Large non-Gaussianities in the Effective Field Theory Approach to Single-Field Inflation: the Trispectrum
We perform the analysis of the trispectrum of curvature perturbations generated by the interactions characterizing a general theory of single-field inflation obtained by effective field theory methods. We find that curvature-generated interaction terms, which can in general give an important contrib...
