Gauge-flation confronted with Planck
Ryo Namba, Emanuela Dimastrogiovanni, Marco Peloso
Gauge-flation is a recently proposed model in which inflation is driven solely by a non-Abelian gauge field thanks to a specific higher order derivative operator. The nature of the…
On the Trispectrum of Galileon Inflation
Frederico Arroja, Nicola Bartolo, Emanuela Dimastrogiovanni +1
We present a detailed study of the trispectrum of the curvature perturbation generated within a stable, well defined and predictive theory which comprises an inflationary phase. In…
The Trispectrum in the Effective Theory of Inflation with Galilean symmetry
Nicola Bartolo, Emanuela Dimastrogiovanni, Matteo Fasiello
We calculate the trispectrum of curvature perturbations for a model of inflation endowed with Galilean symmetry at the level of the fluctuations around an FRW background. Such a mo…
Stability analysis of chromo-natural inflation and possible evasion of Lyth's bound
Emanuela Dimastrogiovanni, Marco Peloso
We perform the complete stability study of the model of chromo-natural inflation (Adshead and Wyman '12), where, due to its coupling to a SU(2) vector, a pseudo-scalar inflaton chi…
