Study on the anomalous quartic W+W− γγ couplings of electroweak bosons in e− p collisions at the LHeC and the FCC-he

Abstract

In this paper, a study is carried out on the e− p → e− γ ∗ p → pW− γνe production to probe quarticW+W− γγ c√ouplings at the LargeHadron electron Collider (LHeC)with s = 1.30, 1.98 TeV and at the Future Circular Colliderhadron electron (FCC-he) with √ s = 3.46, 5.29 TeV. Production cross-sections are determined for both at leptonic and hadronic decay channels of the W-boson.With the data from future e− p colliders, it is possible to obtain sensitivity measures at 95% C.L. on the anomalous fM,i/ 4 and fT, j/ 4 couplings which are competitive with the limits obtained by the LHC, as well as with others limits reported in the literature. The production mode e− p → e− γ ∗ p → pW− γνe in e− p collisions offers a window for study the quartic W+W− γγ electroweak bosons couplings at the LHeC and the FCC-he, which provides a much cleaner collision environment than the LHC.
