Probing the anomalous triple ZZγ and Zγγ couplings at the FCC-μ p and SPPC-μ p

In this study, 24.5 TeV CoM energy FCC-μ p and 20.2 TeV CoM energy SPPC-μ p muon-proton colliders have been utilized to explore the anomalous ZZγ and Zγγ couplings corresponding to dim-8 operators through the process of μ⁻ γ → Z l⁻ → l⁻ νₗ νₗ. A cut-based method has been applied to enhance the signal background ratio in the analysis. Coupling limits, at a 95% Confidence Level (C.L.), under the systematic uncertainties of 0%, 3%, and 5%, were obtained with luminosities of Lᵢₙₜ=5 and 42.8 fb⁻¹ for FCC-μ p and SPPC-μ p colliders, respectively. The limits for anomalous CBB/Λ⁴, CB̃W/Λ⁴, CWW/Λ⁴, CBW/Λ⁴ couplings without systematic uncertainty for FCC-μ p and SPPC-μ p were found as follows, respectively: [0.06845; 0.070019967] TeV-4, [-0.18662; 0.18422] TeV-4, [-0.23623; 0.23815] TeV-4, [-0.61912; 0.62072] TeV-4, and [-0.06606; 0.05050] TeV-4, [-0.15791; 0.15126] TeV-4, [-0.20663; 0.19155] TeV-4, [-0.51383; 0.52211] TeV-4.
