abstract = {We define a minimal model of dark matter with a fermion singlet χ coupled to the
visible sector through the Higgs portal and with a heavy Dirac neutrino N that opens the annihilation
channel χχ → Nν. The model provides the observed relic abundance consistently
with bounds from direct searches and implies a monochromatic neutrino signal at 10 GeV–
1TeV in indirect searches. In particular, we obtain the capture rate of χ by the Sun and show
that the signal could be above the neutrino floor produced by cosmic rays showering in the
solar surface. In most benchmark models this solar astrophysical background is above the expected
dark matter signal, so the model that we propose is a canonical example of WIMP not
excluded by direct searches that could be studied at neutrino telescopes and also at colliders.},
