Abstract

We study the sensitivity of anomalous neutral triple gauge couplings (aNTGC) via $p p \to Z Z$ $pp \rightarrow ZZ$ production in the 4 $ℓ$ $\ell$ channel at 100 TeV center of mass energy of future circular hadron collider, FCC-hh. The analysis including the realistic detector effects is performed in the mode where both Z bosons decay into same-flavor, oppositely charged lepton pairs. The sensitivities to the charge–parity (CP)-conserving couplings $C_{\tilde{B} W} / Λ^{4}$ $C_{{\tilde{B}}W} / \Lambda ^{4}$ and CP-violating couplings $C_{WW} / Λ^{4}$ $C_{WW} / \Lambda ^{4}$ , $C_{BW} / Λ^{4}$ $C_{BW} / \Lambda ^{4}$ and $C_{BB} / Λ^{4}$ $C_{BB} / \Lambda ^{4}$ obtained at 95% Confidence Level using the invariant mass distribution of the 4 $ℓ$ $\ell$ system reconstructing the leading and sub-leading Z boson candidates are $[- 0.09, + 0.09]$ $[-\,0.09, \,\, +\,0.09]$ , $[- 0.21, + 0.21]$ $[-\,0.21, \,\, +\,0.21]$ , $[- 0.26, + 0.26]$ $[-\,0.26, \,\, +\,0.26]$ , and $[- 0.10, + 0.10]$ $[-\,0.10, \,\, +\,0.10]$ in units of ${TeV}^{- 4}$ $\hbox {TeV}^{-4}$ , respectively.
