In this talk, I will introduce the resonant self-interacting dark matter models motivated by observed QCD meson resonant states. I will cover the experimental signatures and astrophysical studies to test these models.  I will then specifically discuss the accelerator searches of these models at the high energy-intensity frontier, using my new experimental proposals, LongQuest and FORMOSA, as examples, and discuss the advantages and complementarity.  Following these new high-energy intensity frontier experiments, I will mention novel neutrino searches at the LHC forward physics region, including Forward Proto-DUNE and other new neutrino experiments, either directly located at the proposed Forward Physics Facility (FPF) or other forward locations with interesting neutrino fluxes.  
Finally, following the discussion of QCD, I would like to discuss a new idea of using exoplanet and trans-Neptunium object orbits to test ultralight axions.  
This talk is based on arXiv:2008.08608, arXiv:1908.07525, arXiv:2010.07941, arXiv:1812.03998, and ongoing works.
