Those models are characterized by the fact that DM interacts with SM particles through renormalizable coupling with an additional heavier charged state. Such interaction allows to produce a substantial abundance of DM in the early Universe via the decay of the charged heavy state, either in- or out-of-equilibrium. Moreover additional couplings of the charged particle open up decay channels for the DM, which can nevertheless be sufficiently long-lived to be a good DM candidate and within reach of future Indirect Detection observations. We compare the cosmologically favored parameter regions to the LHC discovery reach and discuss the possibility of simultaneous detection of DM decay in Indirect Detection."],["dc.description.sponsorship","European Union [PITN-GA-2011-289442]"],["dc.identifier.doi","10.1088/1475-7516/2014/10/063"],["dc.identifier.fs","606275"],["dc.identifier.isi","000345990800064"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11478"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/32068"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Iop Publishing Ltd"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/289442/EU//INVISIBLES"],["dc.relation.issn","1475-7516"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 3.0"],["dc.title","LHC prospects for minimal decaying dark matter"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
