Neutrino Masses and TeV-scale Particles Testable at the LHC

We consider a scenario in which TeV-scale particles belonging to weak-isospin multiplets higher than triplets lead to novel seesaw mechanisms different from conventional type I, II and III seesaw models. Besides an appealing testability of these mechanisms at the LHC, the model with Majorana quintuplets with imposed discrete symmetry may provide viable dark matter candidate.
