We explore a novel possibility that dark matter has a light mass below 1GeV in a lepton portal dark matter model. There are Yukawa couplings involving dark matter, left-handed leptons and an extra scalar doublet in the model. In the light mass region, dark matter is thermally produced via its annihilation into neutrinos. In order to obtain the correct relic abundance and avoid collider bounds, a neutral scalar is required to be light while charged scalars need to be heavier than the electroweak scale. Such a mass spectrum is realized by adjusting quartic couplings in the scalar potential or introducing an extra singlet scalar. It turns out that the mass region of 10MeV-10GeV is almost free from experimental and observational constraints. We also point out that searches for extra neutrino flux from galactic dark matter annihilations with neutrino telescopes are the best way to test our model.

Neutrino portals to MeV WIMPs with s-channel mediators
This paper constructs two new neutrino-portal dark matter models with s-channel scalar and pseudoscalar mediators and maps how JUNO, Hyper-Kamiokande and CMB-S4 would probe their parameter space.

Searching for MeV-mass neutrinophilic Dark Matter with Large Scale Dark Matter Detectors
Xenon-based dark matter detectors, especially DARWIN, could detect neutrinos from MeV-mass dark matter that annihilates to the third neutrino mass eigenstate, with projected sensitivity competitive with Super-Kamiokande.
