# New-Type Charged Q-ball Dark Matter in Gauge Mediated SUSY Breaking Models

## TL;DR

This paper investigates the feasibility of charged Q-balls as dark matter candidates within gauge mediated SUSY breaking models, analyzing observational constraints and theoretical consistency with the Affleck-Dine mechanism.

## Contribution

It introduces a new-type charged Q-ball dark matter scenario and evaluates its viability under experimental constraints and theoretical frameworks.

## Key findings

- Allowed parameter space exists but is smaller than for neutral Q-balls.
- The scenario can be consistent with the Affleck-Dine mechanism.
- Charged Q-balls can evade current experimental constraints.

## Abstract

We examined the viability of new-type charged Q-ball dark matter scenario. We considered the case where the relics can be treated as ordinary ions, to which we applied the observational constraint from MICA experiment, where no trail of heavy ion-like object is observed in $10^9$ years old ancient muscovite mica. We have found that the allowed parameter region exists but is smaller than the neutral Q-ball dark matter case. We have also discussed whether our scenario is actually consistent with Affleck-Dine mechanism.
