TL;DR
This paper explores how modifications in $f(T)$ gravity can facilitate baryogenesis, analyzing different models and their impact on the baryon-to-entropy ratio within cosmological constraints.
Contribution
It introduces a detailed study of $f(T)$ gravity's role in gravitational baryogenesis and examines the effects of generalized cosmologies on the mechanism's viability.
Findings
Certain $f(T)$ models can produce the observed baryon-to-entropy ratio.
Generalized cosmologies can enhance the effectiveness of gravitational baryogenesis.
Constraints from observational data guide viable $f(T)$ gravity models.
Abstract
We investigate how baryogenesis can occur by the presence of an -related gravitational term. We study various cases of gravity and we discuss in detail the effect of the novel terms on the baryon-to-entropy ratio. Additionally, we study the constraints imposed by the observational values of the baryon-to-entropy ratio and we discuss how more generalized cosmologies can contribute successfully, in a viable and consistent way, in the gravitational baryogenesis mechanism.
