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

Understand

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.
