Right-handed neutrinos with MeV to GeV mass are very promising candidates for dark matter (DM). Not only can they solve the missing satellite puzzle, the cusp-core problem of inner DM density profiles, and the too-big-to fail problem, i.e. that the unobserved satellites are too big to not have visible stars, but they can also account for the Standard Model (SM) neutrino masses at one loop. We perform a comprehensive study of the right-handed neutrino parameter space and impose the correct… 

MeV neutrino dark matter in the SLIM model

We explore the parameter space of a variant of the SLIM model, which extends the SM with a singlet and a doublet of complex scalars and two generations of right-handed neutrinos, the lightest of

Cosmology and prospects for sub-MeV dark matter in electron recoil experiments

Author(s): Lehmann, Benjamin V; Profumo, Stefano | Abstract: Dark matter is poorly constrained by direct detection experiments at masses below \SI{1}{\MeV}. This is an important target for the next

Absorption of fermionic dark matter by nuclear targets

Absorption of fermionic dark matter leads to a range of distinct and novel signatures at dark matter direct detection and neutrino experiments. We study the possible signals from fermionic absorption

Lepton flavor violation and scalar dark matter in a radiative model of neutrino masses

We consider a simple extension of the Standard Model that can account for the dark matter and explain the existence of neutrino masses. The model includes a vector-like doublet of SU(2), a singlet

Singlet-doublet fermion and triplet scalar dark matter with radiative neutrino masses

A bstractWe present a detailed study of a combined singlet-doublet fermion and triplet scalar model for dark matter. These models have only been studied separately in the past. Together, they form a

A singlet doublet dark matter model with radiative neutrino masses

A bstractWe present a detailed study of a combined singlet-doublet scalar and singlet-doublet fermion model for dark matter. These models have only been studied separately in the past. We show that

Direct Detection of Leptophilic Dark Matter in a Model with Radiative Neutrino Masses

We consider an electroweak scale model for dark matter (DM) and radiative neutrino mass generation. Despite the leptophilic nature of DM with no direct couplings to quarks and gluons, scattering with

Models with radiative neutrino masses and viable dark matter candidates

A bstractWe provide a list of particle physics models at the TeV-scale that are compatible with neutrino masses and dark matter. In these models, the Standard Model particle content is extended with

Scalar dark matter and fermion coannihilations in the radiative seesaw model

By extending the Standard Model with three right-handed neutrinos (N{sub i}) and a second Higgs doublet (H{sub 2}), odd under a Z{sub 2} symmetry, it is possible to explain non-zero neutrino masses

Minimal model linking two great mysteries: Neutrino mass and dark matter

We present an economic model that establishes a link between neutrino masses and properties of the dark matter candidate. The particle content of the model can be divided into two groups: light

Is it possible to explain neutrino masses with scalar dark matter

We present a scenario in which a remarkably simple relation linking dark matter properties and neutrino masses naturally emerges. This framework points towards a low energy theory where the neutrino
