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 l(-)l(+)gamma and pp -> nu(nu) over bar 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-(B) over tildeW/Lambda(4) and C-BB/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.
