Einstein-Cartan pseudoscalaron inflation, reheating and nonthermal leptogenesis
Carlo Di Benedetto, Alessandro Di Marco, Emanuele Orazi +1
We study the postinflationary dynamics of an Einstein-Cartan-Holst gravity-motivated inflationary scenario, known as Einstein-Cartan pseudoscalaron inflation, coupled to a type-I s…
Introduction to the number of -folds in slow-roll inflation
Alessandro Di Marco, Emanuele Orazi, Gianfranco Pradisi
In this review, a pedagogical introduction to the concepts of slow-roll inflationary Universe and number of -folds is provided. In particular, the differences between the basic…
Einstein-Cartan pseudoscalaron inflation
Alessandro Di Marco, Emanuele Orazi, Gianfranco Pradisi
We study a class of early universe cosmological models based on Einstein-Cartan gravity and including a higher derivative term corresponding to a power of the Holst scalar curvatur…
Minimal Leptogenesis in Brane-inspired Cosmology
Alessandro Di Marco, Amit Dutta Banik, Anish Ghoshal +1
We discuss how a post inflationary reheating phase characterized by a nonstandard multiple scalar field cosmology can change the thermal history of the universe, affecting minimal…
Conformal Metric-Affine Gravities
Gonzalo J. Olmo, Emanuele Orazi, Gianfranco Pradisi
We revisit the gauge symmetry related to integrable projective transformations in metric-affine formalism, identifying the gauge field of the Weyl (conformal) symmetry as a dynamic…
(In)equivalence of Metric-Affine and Metric Effective Field Theories
Gianfranco Pradisi, Alberto Salvio
In a geometrical approach to gravity the metric and the (gravitational) connection can be independent and one deals with metric-affine theories. We construct the most general actio…
