## TL;DR

This study evaluates the sensitivity of future FCC-hh collider experiments to anomalous neutral triple gauge couplings via ZZ production in the four-lepton channel, providing projected bounds at 95% confidence level.

## Contribution

It presents the first detailed sensitivity analysis of anomalous neutral triple gauge couplings at 100 TeV FCC-hh collider including realistic detector effects.

## Key findings

- Projected bounds on CP-conserving couplings are approximately ±0.117 TeV^{-4}.
- Projected bounds on CP-violating couplings range from about ±0.138 to ±0.380 TeV^{-4}.
- Analysis demonstrates the potential of FCC-hh to probe new physics via ZZ production.

## Abstract

We study the sensitivity of anomalous neutral triple gauge couplings ($aNTGC$) via $pp \rightarrow ZZ$ 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 $C_{\tilde{B}W} / \Lambda^{4}$ and CP-violating $C_{WW} / \Lambda^{4}$, $C_{BW} / \Lambda^{4}$ and $C_{BB} / \Lambda^{4}$ 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.
