$$Z_5$$ Z 5 two-component dark matter in the type-II seesaw mechanism

Abstract We consider the $$Z_5$$ Z 5 two-component dark matter model within the framework of the Type-II seesaw mechanism. Due to the new annihilation processes related to triplets, the light component cannot necessarily be dominant in the dark matter relic density, which is different from the two s...
