Collider signatures of fermionic scotogenic dark matter

Abstract

Weakly interacting massive particles (WIMPs) constitute a paradigm in the search for particle dark matter. In contrast to supersymmetry (SUSY), we explore the possibility that WIMP dark-matter acts as mediator of neutrino mass generation. We examine in detail the phenomenology of fermionic dark matter in the revamped (or singlet-triplet) scotogenic model and study its collider implications. Unlike SUSY WIMP dark-matter, collider searches for the Lightest Scotogenic Particle (LSP) at LHC/LHC-HL are strongly complementary to charged lepton flavor violation probes and dark matter studies.
