Sensitivity analysis for the anomalous W^+W^-γ couplings at the LHeC and the FCC-he

We study the anomalous W^+W^-γ couplings in performing the production of the W-pair through the process e^- p → e^-γ ^*γ ^* p → e^-W^+W^-p at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he). We examine the pure hadronic, the semi-leptonic and the pure leptonic decay channels of the produced W-pair. We assume the center-of-mass energies of √(s)=1.30 and 1.98 TeV and the integrated luminosities of 10–100 fb ^-1 for the LHeC and the center-of-mass energies of √(s)=3.46 and 5.29 TeV and the integrated luminosities of 100–2000 fb ^-1 for the FCC-he. The best limits at 95 % confidence level obtained for the anomalous couplings Δκ _γ and λ _γ are Δκ _γ=[-0.00208; 0.00206] and λ _γ=[- 0.00174; 0.00834] . By comparing these limits with the experimental limits, we present the potentials of the process and future ep colliders.
