|TITLE||Charged Q-ball dark matter in gauge mediation models|
We consider charged Q-ball dark matter scenario, which is realized after the Affleck-Dine baryogenesis through the partial decay of Q-balls. We focus on the fact that these objects are detectable by the usual electromagnetic processes, unlike the ordinary neutral Q-balls. We apply the most stringent constraint from the MICA experiment to the model where the charged Q-balls are realized. We find that the MICA constraint is severer than those from IceCube, which probe neutral Q-ball process, leading to the smaller allowed parameter region.
