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…
Topological densities in Einstein-scalar-Gauss-Bonnet gravity
M. Bousder, Z Sakhi
The present work is devoted to studying the background dynamical evolution of a scalar field in Einstein-Gauss-Bonnet gravity in maximally symmetric space-time. This study is usefu…
Signatures of the Early Universe: Uncovering Cosmological Footprints
K. El Bourakadi, Z. Sakhi, M. Bennai
The post-inflationary epochs are critical for comprehending the early evolution of our Universe. This article delves into the cosmological signatures that shed light on these early…
Observational constraints on Tachyon inflation and reheating in f(Q) gravity
K. El Bourakadi, Z. Sakhi, M. Bennai
In this work we study one of the most appealing string theory-motivated models, we present a tachyonic inflationary model in the recently proposed symmetric teleparallel framework,…
Primordial black holes and gravitational waves in teleparallel Gravity
K. El Bourakadi, B. Asfour, Z. Sakhi +2
In this paper, we consider the possible effect of the teleparallel gravity on the production of the primordial black holes (PBH) and on the gravitational waves (GWs). We investigat…
Preheating constraints in -attractor inflation and Gravitational Waves production
K. El Bourakadi, Z. Sakhi, M. Bennai
We propose a scenario where preheating occurs for a specific duration that is parametrized by an e-folds number , our results suggest a direct correlation between the preh…
Gravitational Waves from Preheating in Gauss-Bonnet Inflation
K. El Bourakadi, M. Ferricha-Alami, H. Filali +2
We study gravitational wave production in an expanding Universe during the first stages following inflation, and investigate the consequences of the Gauss-Bonnet term on the inflat…
Quintessence like behavior of symmetric teleparallel dark energy: Linear and nonlinear model
A. Hanin, M. Koussour, Z. Sakhi +1
In Einstein's General Relativity (GR), the gravitational interactions are described by the spacetime curvature. Recently, other alternative geometric formulations and representatio…

M. Koussour, S. H. Shekh, A. Hanin +3
In this paper, we investigate the homogeneous and isotropic flat FLRW Universe in the logarithmic form of gravity, where is the non-metricity scalar, spe…
Preheating and Reheating Constraints in Supersymmetric Braneworld Inflation
K. El Bourakadi, M. Bousder, Z. Sakhi +1
We study the evolution of the Universe at early stages, we discuss also preheating in the framework of hybrid braneworld inflation by setting conditions on the coupling constants $…
A new unified model of dark matter and dark energy in 5-dimensional gravity
M. Bousder, Z. Sakhi, M. Bennai
We propose a new unified model that describes~dark energy and dark matter in the context of gravity using a massive scalar field in five dimensions. The scalar field is co…
