We study the DM-neutrino interaction in the framework of simplified model.
The phenomenology of such an interaction are derived. We also investigate the
bound on DM-neutrino interaction from the LHC and neutrino telescopes. We find
that for the case of a scalar dark matter, the LHC gives a stronger bound on
dark matter annihilation cross-section than the neutrino telescopes. However,
for the fermionic dark matter case the neutrino telescopes bounds are more
stringent for dark matter mass, ≳200 MeV. In the case of lower DM
mass, the neutrino telescopes provide better bounds for a light mediator, while
the collider bounds are better for a heavy mediator. Possible UV completions of
the simplified model are briefly discussed.Comment: 23 pages, 12 figures. Add discussion on DM-neutrino interaction.
