Affleck-Dine baryogenesis with modulated reheating

TL;DR

This paper investigates how Affleck-Dine baryogenesis can be compatible with the modulated reheating scenario, which predicts observable primordial non-Gaussianity and tensor fluctuations, by analyzing baryonic-isocurvature fluctuations.

Contribution

It demonstrates the consistency of Affleck-Dine baryogenesis with modulated reheating under current observational constraints on isocurvature fluctuations.

Findings

Affleck-Dine baryogenesis can coexist with modulated reheating.

Current observations do not rule out this scenario.

The model predicts potential signals in future CMB experiments.

Abstract

Modulated reheating scenario is one of the most attractive models that predict possible detections of not only the primordial non-Gaussianity but also the tensor fluctuation through future CMB observations such as the Planck satellite, the PolarBeaR and the LiteBIRD satellite experiments. We study the baryonic-isocurvature fluctuations in the Affleck-Dine baryogenesis with the modulated reheating scenario. We show that the Affleck-Dine baryogenesis can be consistent with the modulated reheating scenario with respect to the current observational constraint on the baryonic-isocurvature fluctuations.
