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

Abstract

The effects of dimension-eight operators giving rise to anomalous neutral triple gauge boson interactions of $Z{\hat{I}}^3{\hat{I}}^3$ and $Z{\hat{I}}^{3}Z$ vertices in $pp\to l^{-}{l}^{+}{\hat{I}}^3$ and $pp\to \hat{I}½\bar{\hat{I}}½{\hat{I}}^3$ are investigated at 100 TeV centre of mass energy of future circular hadron collider (FCC-hh). The transverse momentum of photon, invariant mass of $l^{-}{l}^{+}{\hat{I}}^3$ 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 $C_{\tilde{B}W}/\hat{I}{›}^4$ and $C_{BB}/\hat{I}{›}^4$ 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.
