Tracing Inflationary Imprints Through the Dark Ages: Implications for Early Stars and Galaxies Formation
K. El Bourakadi, M. Yu. Khlopov, M. Krasnov +2
We explore how inflationary features shape the early stages of cosmic structure formation. Using the transfer function formalism, we trace the evolution of primordial perturbations…
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…
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…
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,…
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…
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…
On Braneworld Inflation Models in Light of WMAP7 data
R. Zarrouki, Z. Sakhi, M. Bennai
We are interested on studing various inflationary spectrum perturbation parameters in the context of the Randall-Sandrum type 2 Braneworld model. We consider in particular three ty…
Chaplygin gas braneworld inflation according to WMAP7 data
R. Zarrouki, M. Bennai
We consider a Chaplygin gas model with an exponential potential in framework of braneworld inflation. We apply the slow-roll approximation in the high-energy limit to derive variou…
