We take into account the presence of exotic and invisible decays of the Z0 gauge boson to find a more conservative and robust limit, different from previous studies. We investigate the impact of these new decay channels for several benchmark models in the scope of two different 3-3-1 models. We found that in the most constraining cases, LHC with 139 fb−1 can impose mZ0 > 4 TeV. Moreover, we forecast high-luminosity LHC, high-energy LHC, and Future Circular Collider reach, and derive the projected bounds mZ0 > 5.8 TeV, mZ0 > 9.9 TeV, and mZ0 > 27 TeV, respectively. Lastly, we put our findings into perspective with dark matter searches to show the region of parameter space where a dark matter candidate with the right relic density is possible.enLarge Hadron Collider (LHC)Collider3-3-1 models3-3-1 RHN3-3-1 LHNArtículoAtribution 4.0 International (CC BY 4.0)DOI: 10.1103/PhysRevD.106.055027
