Abstract

We discuss the phenomenology of a minimal model for GeV-scale Majorana dark matter (DM) coupled to the standard model lepton sector via a charged scalar singlet. The theoretical framework extends the Standard Model by two SU(2)_L singlets: one charged Higgs boson and a singlet right-handed fermion. The latter plays the role of the DM candidate. We show that there is an anti-correlation between the spin-independent DM-Nucleus scattering cross-section (σ_{\rm SI}) and the DM relic density. We suggest a scenario that can be tested in both electron-electron and electron-positron collisions using the production of same-sign charged Higgs pairs and mono-Higgs in association with right-handed neutrinos.
