“…The fermionic dark matter case mimics neutralino dark matter in supersymmetry [9] and has been recently re-visited in Refs. [13][14][15]. As we will see, scalar WIMP dark matter phenomenology in the Singlet + Triplet Scotogenic Model provides a rich scenario, sharing common features with other dark matter models such as the Inert Higgs Doublet Model [16][17][18][19][20] and with discrete dark matter models [21,22].…”

“…where θ is the mixing angle between the neutral fermion triplet 0 and F, M and M F are the Majorana mass terms for the triplet and the singlet, respectively. Although we will not consider this case here, it is interesting to notice that the lightest neutral eigenstate, χ 0 1 or χ 0 2 may also play the role of the dark matter [9], for more recent analyses see [13,14].…”

We reexamine the minimal Singlet $$+$$ + Triplet Scotogenic Model, where dark matter is the mediator of neutrino mass generation. We assume it to be a scalar WIMP, whose stability follows from the same $${\mathbb {Z}}_{2}$$ Z 2 symmetry that leads to the radiative origin of neutrino masses. The scheme is the minimal one that allows for solar and atmospheric mass scales to be generated. We perform a full numerical analysis of the signatures expected at dark matter as well as collider experiments. We identify parameter regions where dark matter predictions agree with theoretical and experimental constraints, such as neutrino oscillations, Higgs data, dark matter relic abundance and direct detection searches. We also present forecasts for near future direct and indirect detection experiments. These will further probe the parameter space. Finally, we explore collider signatures associated with the mono-jet channel at the LHC, highlighting the existence of a viable light dark matter mass range.

“…To demonstrate the feature of such cases, we have considered a specific example, where the SM is extended by an SU(2) L real triplet fermion Σ = (Σ 1 , Σ 2 , Σ 3 ). This additional DOF plays a central role in the generation of neutrino masses and mixing [87,[94][95][96][97][98][99][100], lepton flavour violating decays [101][102][103][104][105][106][107], explaining dark matter [108][109][110][111], and CP & matter-antimatter asymmetry [112][113][114][115]. In most of these scenarios, this JHEP01(2021)028 triplet fermion is accompanied by other particles which can be integrated out to construct an effective Lagrangian described by SM DOFs and Σ.…”

It is not only conceivable but likely that the spectrum of physics beyond the Standard Model (SM) is non-degenerate. The lightest non-SM particle may reside close enough to the electroweak scale that it can be kinematically probed at high-energy experiments and on account of this, it must be included as an infrared (IR) degree of freedom (DOF) along with the SM ones. The rest of the non-SM particles are heavy enough to be directly experimentally inaccessible and can be integrated out. Now, to capture the effects of the complete theory, one must take into account the higher dimensional operators constituted of the SM DOFs and the minimal extension. This construction, BSMEFT, is in the same spirit as SMEFT but now with extra IR DOFs. Constructing a BSMEFT is in general the first step after establishing experimental evidence for a new particle. We have investigated three different scenarios where the SM is extended by additional (i) uncolored, (ii) colored particles, and (iii) abelian gauge symmetries. For each such scenario, we have included the most-anticipated and phenomenologically motivated models to demonstrate the concept of BSMEFT. In this paper, we have provided the full EFT Lagrangian for each such model up to mass dimension 6. We have also identified the CP, baryon (B), and lepton (L) number violating effective operators.

Phenomenological and cosmological implications of a scotogenic three-loop neutrino mass model

We propose a scotogenic model for generating neutrino masses through a three-loop seesaw. It is a minimally extended inert doublet model with a spontaneously broken global symmetry U(1)′ and a preserved ℤ2 symmetry. The three-loop suppression allows the new particles to have masses at the TeV scale without fine-tuning the Yukawa couplings. The model leads to a rich phenomenology while satisfying all the current constraints imposed by neutrinoless double-beta decay, charged-lepton flavor violation, and electroweak precision observables. The relatively large Yukawa couplings lead to sizable rates for charged lepton flavor violation processes, well within future experimental reach. The model could also successfully explain the W mass anomaly and provides viable fermionic or scalar dark matter candidates.
