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 Zγγ and ZγZ vertices in pp→l−l+γ and pp→νν¯γ 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+γ 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 CB˜W/Λ4 and CBB/Λ4 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 Lint=1 (3) ab−1, respectively.
