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 Zγγ and ZγZ vertices in $pp\to {l}^{-}{l}^{+}\gamma $ and $pp\to \nu \overline{\nu }\gamma $ are investigated at 100 TeV center 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 ${C}_{\stackrel{˜}{B}W}/{\Lambda }^{4}$ and ${C}_{BB}/{\Lambda }^{4}$ couplings are $\left[-0.52;0.52\right]\left(\left[-0.40;0.40\right]\right)$ TeV$^{−4}$, $\left[-0.43;0.43\right]\left(\left[-0.33;0.33\right]\right)$ TeV$^{−4}$ in the dilepton+photon channel and $\left[-0.11;0.11\right]\left(\left[-0.084;0.084\right]\right)$ TeV$^{−4}$, $\left[-0.092;0.092\right]\left(\left[-0.072;0.072\right]\right)$ TeV$^{−4}$ in the MET+photon channel with ${L}_{int}=1$ (3) ab$^{−1}$, respectively.
