  "abstract": "We present a phenomenological study of the discovery potential at the FCC-hh for a new heavy neutral vector boson, $$Z^{\\prime }$$ Z ′ , predicted by the $$U(1)_{B-L}$$ U ( 1 ) B - L gauge symmetry. Focusing on the parameter space currently not excluded by Large Hadron Collider data, we analyze the dilepton production channel $$p p \\rightarrow Z^{\\prime } \\rightarrow l^{+} l^{-}$$ p p → Z ′ → l + l - ( $$l^{\\pm } = e^{\\pm }, \\mu ^{\\pm }$$ l ± = e ± , μ ± ) at a center-of-mass energy of $$\\sqrt{s} = 100$$ s = 100 TeV. Full Monte Carlo simulations were performed for different ( $$M_{Z'}$$ M Z ′ , $$g_{B-L}$$ g B - L ) BSM scenarios and relevant Standard Model backgrounds (including irreducible Drell-Yan, diboson, single top-quark and top-quark pair productions), identifying optimal kinematic selection cuts to guide future searches for this type of resonance. We estimate the FCC-hh reach for an integrated luminosity of $$\\mathcal {L}_{int}$$ L int = 30 $$ab^{-1}$$ a b - 1 . Our results demonstrate that the FCC-hh at full operation can exclude $$Z^{\\prime }$$ Z ′ masses up to $$\\sim $$ ∼ 50 TeV with 95% C.L. for couplings of $$g_{B-L} \\sim 1$$ g B - L ∼ 1 , and up to $$\\sim $$ ∼ 30 TeV for $$g_{B-L} \\sim 0.1$$ g B - L ∼ 0.1 . We find the kinematic cuts that optimize the signal over background ratio and achieve a $$5\\sigma $$ 5 σ signal up to $$Z^{\\prime }$$ Z ′ masses of $$\\sim $$ ∼ 40 TeV. These findings highlight the FCC-hh potential to uncover new physics signals in the high-mass regime.",
