Large non-Gaussianities in the Effective Field Theory Approach to Single-Field Inflation: the Trispectrum
Nicola Bartolo, Matteo Fasiello, Sabino Matarrese +1
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…

Large non-Gaussianities in the Effective Field Theory Approach to Single-Field Inflation: the Bispectrum
Nicola Bartolo, Matteo Fasiello, Sabino Matarrese +1
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field and to perform a general analysis of the associated non-Gaussiani…
