In this paper, we investigate D-term inflation within the framework of supergravity, employing the minimal Kahler potential. Our study reveals that this model can overcome the {\eta}-problem found in F-term models. Additionally, we explore reheating

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 gravitational waves align well with the recent observations of a stochastic

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 was found that by considering a specific reheating temperature, the o

The post-inflationary epochs are crucial for understanding the primordial evolution of our Universe. In this article, we explore the cosmological signatures that can provide insight into the early epochs, specifically focusing on the production of se

This article investigates the effects of Tree Level Higgs Potential on reheating in $f(Q)$ gravity. We examine the formalism of tree level inflation in a modified $f(Q)$ model, finding that the slow roll and e-folds number during inflation depend on

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, and examine constraints on tachyon inflation with the exponential pot

In this study, we investigate the consequence of the constant-roll condition and examine the role of $f(Q,T)$ gravity in the cosmological inflation process. We analyze the inflationary scenario by calculating modified Friedmann equations, and giving

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 investigate the relationship between the slow roll, the e-folds number and the t

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 inflationary parameters for a power-law inflation model with a GB coupling t

We propose a scenario where preheating occurs for a specific duration that is parametrized by an e-folds number $N_{pre}$, our results suggest a direct correlation between the preheating duration and the density of gravitational waves (GWs) produced
