An explicit model is built where Dirac fermion dark matter semi-annihilates to boosted dark matter plus neutrinos, with two-loop radiative neutrino masses, requiring a mediator mass of O(1) MeV to reach O(10^{-36}) cm² scattering cross section detectable in DUNE and DARWIN.

abstract
We investigate a Z3 symmetric model with two-loop radiative neutrino masses. Dark matter in the model is either a Dirac fermion or a complex scalar as a result of an unbroken Z3 symmetry. In addition to standard annihilation processes, semi-annihilation of the dark matter contributes to the relic density. We study the effect of the semi-annihilation in the model and and that those contributions are important to obtain the observed relic density. The experimental signatures in dark matter searches are also discussed, where some of them are expected to be different from the signatures of dark matter in Z2 symmetric models.

Boosted dark matter via semi-annihilation in a radiative neutrino mass model
An explicit model is built where Dirac fermion dark matter semi-annihilates to boosted dark matter plus neutrinos, with two-loop radiative neutrino masses, requiring a mediator mass of O(1) MeV to reach O(10^{-36}) cm² scattering cross section detectable in DUNE and DARWIN.
