Probing of Zγγ production sensitivity to anomalous quartic gauge couplings at LHC experiments with √ s =13 TeV

Аннотация

Sensitivity to anomalous ZZγγ and Zγγγ couplings in Zγγ production was probed for the ATLAS experiment at Large Hadron Collider. Zγγ process with anomalous couplings simulation in ppcollisions with √ s = 13 TeV was performed using VBFNLO MC generator. The expected limits on the Effective Field Theory parameters f_T0/Λ4, f_T5/Λ4, f_T9/Λ4, f_M2/Λ4, f_M3/Λ4 were extracted for 5 fb⁻¹ integral luminosity using the distribution on the invariant mass of Zγγ from the combination of charged leptonic decay channels of Z boson (Zγγ → μ⁺μ⁻γγ and Zγγ → e⁺e⁻γγ).
