Dark matter and baryogenesis in the Fermi-bounce curvaton mechanism
Andrea Addazi, Stephon Alexander, Yi-Fu Cai, Antonino Marciano
TL;DR
This paper presents a toy-model of matter bounce involving two fermion species with four-fermion interactions, proposing a curvaton mechanism and a potential explanation for baryogenesis and dark matter constraints.
Contribution
It introduces a novel fermionic matter bounce model with a built-in curvaton mechanism and baryogenesis, linking fermion species to dark matter and baryon asymmetry.
Findings
Proposes a fermionic matter bounce model with two species.
Demonstrates a curvaton mechanism within the model.
Suggests one fermion species can account for baryogenesis and dark matter constraints.
Abstract
We elaborate on a toy-model of matter bounce, in which the matter content is constituted by two fermion species endowed with four fermion interaction term. We describe the curvaton mechanism that is forth generated, and then argue that one of the two fermionic species may realize baryogenesis, while the other (lighter) one is compatible with constrains on extra hot dark matter particles.
