This paper presents the projections on the anomalous neutral triple gauge couplings (aNTGC) via pp→ZZ production in the 2ℓ2ν final state at a 100 TeV proton-proton collider, FCC-hh. The realistic FCC-hh detector environments and its effects taken into account in the analysis. The study is carried out in the mode where one Z boson decays into a pair of same-flavor, opposite-sign leptons (electrons or muons) and the other one decays to the two neutrinos. The new bounds on the charge-parity (CP)-conserving couplings CB˜W/Λ4 and CP-violating couplings CWW/Λ4, CBW/Λ4 and CBB/Λ4 achieved at 95% Confidence Level (C.L.) using the transverse momentum of the dilepton system (pTℓℓ) are [−0.042,+0.042], [−0.049,+0.049], [−0.048,+0.048], and [−0.047,+0.047] in units of TeV−4, respectively.
