We propose a minimal model of a fermionic dark matter with a pseudoscalar mediator and N generation of vector-like quarks. We calculate the relic density and obtain a new constraint on the generation of the vector-like quarks. From the viewpoint of phenomenology, we probe the proposed model via direct and indirect approaches. Finally, as an illustrative example, we evaluate a resonance case — the subject of major experiments designed for detection of new particles. Our analysis results in significant constraints on the coupling strength of vector-like quarks.
