Analysis of baryon to entropy ratio in Ricci inverse gravity

Abstract

Abstract This letter is devoted to investigate the matter-antimatter asymmetry through baryogenesis (and generalized gravitational baryogenesis interaction) in the realm of f(R, A) theory of gravity also known as Ricci inverse gravity, where R is the curvature scalar and A is the anti-curvature scalar. Baryogensis (baryon to entropy ratio ) is a theoretical process that took place in the early history of the universe producing supremacy of matter over anti-matter, where S is entropy of universe and is the baryon (anti-baryon) number. In this article, we inspect the consequences of interactions proportional to and . We take as specific model to analyze the phenomenon of baryogenesis and generalized gravitational baryogenesis. Our outcomes show that f(R, A) gravity can come up consistently and significantly to the phenomenon of gravitational baryogenesis. We compare our results with latest astrophysical data of baryon to entropy ratio, which exhibits outstanding compatibility with the observational bounds.
