Resumen
In this work, we derive lower mass bounds on the Z0 gauge boson based on the dilepton data from
the Large Hadron Collider (LHC) with 13 TeV of center-of-mass energy, and forecast the sensitivity of the
high-luminosity LHC with L ¼ 3000 fb−1, the high-energy LHC with ffiffi
s p ¼ 27 TeV, and also at the
Future Circular Collider with ffiffi
s p ¼ 100 TeV. 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.
