Q-ball dark matter and baryogenesis in high-scale inflation

TL;DR

This paper explores a high-scale inflation scenario where Q balls from flat directions generate dark matter and baryon asymmetry, with potential detection prospects in IceCube-like experiments.

Contribution

It proposes a novel model linking Q-ball dark matter and baryogenesis in high-scale inflation, with suppressed isocurvature fluctuations and testable predictions.

Findings

Q balls can account for dark matter in high-scale inflation scenarios.

Isocurvature fluctuations are suppressed by the Affleck-Dine field dynamics.

Future IceCube-like experiments could detect these dark matter Q balls.

Abstract

We investigate the scenario that one flat direction creates baryon asymmetry of the unverse, while Q balls from another direction can be the dark matter in the gauge-mediated supersymmetry breaking for high-scale inflation. Isocurvature fluctuations are suppressed by the fact that the Affleck-Dine field stays at around the Planck scale during inflation. We find that the dark matter Q balls can be detected in IceCube-like experiments in the future.
