Distinctive signatures of space-time diffeomorphism breaking in EFT of inflation
Nicola Bartolo, Dario Cannone, Angelo Ricciardone +1
The effective field theory of inflation is a powerful tool for obtaining model independent predictions common to large classes of inflationary models. It requires only information…
Generalised tensor fluctuations and inflation
Dario Cannone, Gianmassimo Tasinato, David Wands
Using an effective field theory approach to inflation, we examine novel properties of the spectrum of inflationary tensor fluctuations, that arise when breaking some of the symmetr…
Mild quasi-local non-Gaussianity as a signature of modified gravity during inflation
Nicola Bartolo, Dario Cannone, Raul Jimenez +2
We show that modifications of Einstein gravity during inflation could leave potentially measurable imprints on cosmological observables in the form of non-Gaussian perturbations. T…
Perturbative Unitarity of Inflationary Models with Features
Dario Cannone, Nicola Bartolo, Sabino Matarrese
We consider the pertubative consistency of inflationary models with features with effective field theory methods. By estimating the size of one-loop contributions to the three-poin…
The Effective Field Theory of Inflation Models with Sharp Features
Nicola Bartolo, Dario Cannone, Sabino Matarrese
We describe models of single-field inflation with small and sharp step features in the potential (and sound speed) of the inflaton field, in the context of the Effective Field Theo…
