| contents | We propose a minimal extension of the Standard Model (SM) that addresses both the smallness of neutrino masses and the dark matter (DM) puzzle via the inverse seesaw mechanism and an axion portal fermionic DM. This model generates light neutrino masses without requiring high energy scales, enhancing its testability in future collider experiments. An axion-like particle (ALP) connects the SM and DM sectors, yielding a distinct phenomenology. Our analysis shows that the model is consistent with constraints from neutrino oscillations and DM relic density as well as satisfying the current measurement on muon $g-2$. This work offers a unified framework to address neutrino masses and DM, with implications for particle physics and cosmology. |
