Probing the Effects of Dimension-eight Operators Describing Anomalous Neutral Triple Gauge Boson Interactions at FCC-hh

The effects of dimension-eight operators giving rise to anomalous neutral triple gauge boson interactions of $Z\gamma \gamma$ and $Z\gamma Z$ vertices in $pp\to l^{-}{l}^{+}\gamma$ and $pp\to \nu \bar{\nu }\gamma$ are investigated at 100 TeV centre of mass energy of future circular hadron collider (FCC-hh). The transverse momentum of photon, invariant mass of $l^{-}{l}^{+}\gamma$ and angular distribution of charged lepton in the rest frame of $l^{-}{l}^{+}$ and Missing Energy Transverse (MET) are considered in the analysis. The realistic detector effects are also included with Delphes simulation. Sensitivity limits obtained at 95% C.L. for $C_{\tilde{B}W}\mathrm{/}{\mathrm{\Lambda }}^4$ and $C_{BB}\mathrm{/}{\mathrm{\Lambda }}^4$ couplings are $[-0.52;0.52]([-0.40;0.40])$ TeV${}^{-4}$, $[-0.43;0.43]([-0.33;0.33])$ TeV${}^{-4}$ in the dilepton+photon channel and $[-0.11;0.11]([-0.084;0.084])$ TeV${}^{-4}$, $[-0.092;0.092]([-0.072;0.072])$ TeV${}^{-4}$ in the MET+photon channel with $L_{int}$=1 (3) ab${}^{-1}$, respectively.
