Sensitivity analysis for the anomalous $$W^+W^- \\gamma $$ couplings at the LHeC and the FCC-he

Abstract

We study the anomalous couplings in performing the production of the W-pair through the process 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 and 1.98 TeV and the integrated luminosities of 10–100 fb for the LHeC and the center-of-mass energies of and 5.29 TeV and the integrated luminosities of 100–2000 fb for the FCC-he. The best limits at 95 confidence level obtained for the anomalous couplings and are and . By comparing these limits with the experimental limits, we present the potentials of the process and future ep colliders.
