Insights into Gravitinos Abundance, Cosmic Strings and Stochastic Gravitational Wave Background
K. El Bourakadi, G. Otalora, A. Burton-Villalobos +3
In this paper, we investigate D-term inflation within the framework of supergravity, employing the minimal Kähler potential. Following previous studies that revealed that this mode…

Leptogenesis Effects on the Gravitational Waves Background: Interpreting the NANOGrav Measurements and JWST Constraints on Primordial Black Holes
K. El Bourakadi, H. Chakir, M. Yu. Khlopov
We demonstrate that the leptogenesis mechanisms, which are associated with B-L symmetry breaking mechanism has notable effects on the production of gravitational waves. These gravi…

Dark matter via Baryogenesis: Affleck-Dine Mechanism in the Minimal Supersymmetric Standard Model
K. El Bourakadi, M. Ferricha-Alami, Z. Sakhi +2
We conducted an investigation into Affleck-Dine baryogenesis within the context of D-term inflation, specifically focusing on its relationship with a recent reheating formalism. It…
