New type of charged Q-ball dark matter in gauge mediated SUSY breaking models
AbstractWe examined the viability of a new type of 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 the MICA experiment, where no trail of heavy ionlike object is observed in 109 year-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.
