We examine simple extension of the standard model with a pair of fermions, one singlet and a doublet, in a common thread linking the dark matter problem with the smallness of neutrino masses associated with several exciting features. In the presence of a small bare Majorana mass term, the singlet fermion brings in a pseudo-Dirac dark matter capable of evading the strong spin-independent direct detection bound by suppressing the dark matter annihilation processes mediated by the neutral current. In consequence, the allowed range of mixing angle between the doublet and the singlet fermions gets enhanced substantially. Presence of the same mass term in association of singlet scalars also elevates tiny but nonzero masses radiatively for light Majorana neutrino satisfying observed oscillation data.

Coscattering Dark Matter in the Inverse Scotogenic Models
In the inverse scotogenic model, nearly degenerate Z2-odd scalars φ1 and φ2 produce the observed dark matter relic density via coscattering through either the Higgs portal or Yukawa portal, with long-lived φ2 decays g...

Impact of conversion-driven processes on singlet-doublet Majorana dark matter relic
For Majorana singlet-doublet dark matter, including conversion-driven processes enlarges the relic-density- and direct-detection-allowed mixing range to sinθ≈2×10^-7–0.16 for M_DM up to ~1750 GeV.
