Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark matter candidates. No conclusive signal, despite an extensive search program that combines, often in a complementary way, direct, indirect, and collider probes, has been detected so far. This situation might change in near future due to the advent of one/multi-TON Direct Detection experiments. We thus, find it timely to provide a review of the WIMP paradigm with focus on a few models which can be probed at best by these facilities. Collider and Indirect Detection, nevertheless, will not be neglected when they represent a complementary probe.

“…Our model is similar to the bino-higgsino scenario in the minimal supersymmetric standard model (MSSM) [13], except that the couplings are not set by supersymmetry, but free parameters. The singlet-doublet model has received a lot of attention, due to its interesting phenomenology in the context of dark matter [14][15][16][17], baryogenesis [18,19], and observation prospects at colliders [16,20,21]. Besides those virtues, it provides naturally strong renormalizable interactions between the dark fermions and the Higgs boson.…”

Where collider searches for resonant invisible particles lose steam, dark sectors might leave their trace as virtual effects in precision observables. Here we explore this option in the framework of Higgs portal models, where a sector of dark fermions interacts with the standard model through a strong renormalizable coupling to the Higgs boson. We show that precise measurements of Higgs-gauge and triple Higgs interactions can probe dark fermions up to the TeV scale through virtual corrections. Observation prospects at the LHC and future lepton colliders are discussed for the so-called singlet-doublet model of Majorana fermions, a generalization of the bino-higgsino scenario in supersymmetry. We advocate a two-fold search strategy for dark sectors through direct and indirect observables.

“…1 The minimal module consists of a single odd-dimensional SU(2) L representation Weyl fermion together with a vector-like pair (such that anomalies cancel) of even-dimensional representations with an appropriate hypercharge. Two such constructions which have been previously considered are singlet-doublet dark matter [12][13][14][15][16][17] and doublet-triplet dark matter [17,18]. Both of these sets look (in the appropriate limit) like subsets of the neutralino sector of the minimal supersymmetric standard model (MSSM), and share some of its phenomenology.…”

We explore a dark matter model extending the standard model particle content by one fermionic SU(2) L triplet and two fermionic SU(2) L quadruplets, leading to a minimal realistic UV-complete model of electroweakly interacting dark matter which interacts with the Higgs doublet at tree level via two kinds of Yukawa couplings. After electroweak symmetry-breaking, the physical spectrum of the dark sector consists of three Majorana fermions, three singly charged fermions, and one doubly charged fermion, with the lightest neutral fermion χ 0 1 serving as a dark matter candidate. A typical spectrum exhibits a large degree of degeneracy in mass between the neutral and charged fermions, and we examine the one-loop corrections to the mass differences to ensure that the lightest particle is neutral. We identify regions of parameter space for which the dark matter abundance is saturated for a standard cosmology, including coannihilation channels, and find that this is typically achieved for m χ 0 1 ∼ 2.4 TeV. Constraints from precision electroweak measurements, searches for dark matter scattering with nuclei, and dark matter annihilation are important, but leave open a viable range for a thermal relic.
