Sensitivity on Anomalous Neutral Triple Gauge Couplings via $ZZ$ Production at FCC-hh

Abstract

We study the sensitivity of anomalous neutral triple gauge couplings ($aNTGC$) via $pp\to ZZ$ production in the 4$\ell$ channel at 100 TeV centre of mass energy of future circular hadron collider, \verb"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 $C_{\tilde{B}W}/\hat{I}{›}^4$ and CP-violating $C_{WW}/\hat{I}{›}^4$, $C_{BW}/\hat{I}{›}^4$ and $C_{BB}/\hat{I}{›}^4$ couplings obtained at 95\% Confidence Level (C.L.) using the invariant mass distribution of 4$\ell$ system reconstructing the leading and sub-leading Z boson candidates are $[-0.117,+0.117]$, $[-0.293,+0.292]$, $[-0.380,+0.379]$, and $[-0.138,+0.138]$ in the unit of TeV${}^{-4}$, respectively.
