Gravitational baryogenesis of vacuum Inflation
Zhiqiang Huang, Qing-yu Cai

TL;DR
This paper demonstrates that gravitational baryogenesis within the vacuum inflation model can naturally generate the observed baryon asymmetry, aligning the baryon-to-entropy ratio with cosmological observations.
Contribution
It introduces a novel application of gravitational baryogenesis to vacuum inflation, providing a natural explanation for the decoupling temperature and baryon asymmetry.
Findings
The mechanism produces acceptable baryon-to-entropy ratios.
Analysis of entropy and baryon number evolution supports the model.
Comparison of dilution speed and chemical potential explains decoupling temperature.
Abstract
We show that in the vacuum inflation model, the gravitational baryogenesis mechanism will produce the baryon asymmetry. We analyze the evolution of entropy and baryon number in the vacuum inflation model. The comparison between dilution speed and the chemical potential may give a natural interpretation for decouple temperature of the gravitational baryogenesis interaction. From the result, the mechanism can give acceptable baryon-to-entropy ratio in the vacuum inflation model.
