Dark Matter Searches as New Physics at the Future Circular Collider (FCC)

Abstract We highlight the importance of the Future Circular Collider (FCC) in the search for possible Dark Matter (DM) signatures. The focus will be on well motivated Beyond the Standard Model (BSM) extensions. We consider a class of radiative neutrino mass models which extend the SM by adding heavy right handed neutrinos (RHNs), where the neutrino masses are generated at loop level. Within this class of models, the lightest RHN is considered to be stable and serves as DM candidate. We perform preliminary studies of final states which involve missing energy contributions from DM candidates to learn about the feasibility of observing these final states at the expected FCC-hh, FCC-eh and FCC-ee beam colliders. Some of our results are discussed where the topology of the the final states are analysed depending on the obtained sensitivity of the signal. The study also yields the most common promising discovery channels in exploring potential indirect DM signatures at future lepton and hadron colliders.
