“…In the direct Z/γ production process, the anomalous WWZ and WWγ couplings can be separately measured without being influenced by their interference [465,466]. In the direct W production process, both the deviation in the signal cross-section and the kinematic distributions can effectively constrain the WWγ aTGC, while anomalous WWZ contribution in this channel is insensitive as a result of the suppression due to the Z boson mass [467][468][469].…”

“…When compared with the current LHC (blue and green) and LEP collider (red) bounds, the LHeC has the potential to significantly improve the constraints, in particular, those imposed on the Δκ γ parameter. The polarised electron beam is found to improve the aTGC measurement [ 466,469]. In consideration of the realistic analysis at detector level, one can expect 2-3 ab −1 of integrated luminosity to achieve the same results [467].…”

The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron–proton and proton–proton operations. This report represents an update to the LHeC’s conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LHeC will open a new chapter of nuclear particle physics by extending the accessible kinematic range of lepton–nucleus scattering by several orders of magnitude. Due to its enhanced luminosity and large energy and the cleanliness of the final hadronic states, the LHeC has a strong Higgs physics programme and its own discovery potential for new physics. Building on the 2012 CDR, this report contains a detailed updated design for the energy-recovery electron linac (ERL), including a new lattice, magnet and superconducting radio-frequency technology, and further components. Challenges of energy recovery are described, and the lower-energy, high-current, three-turn ERL facility, PERLE at Orsay, is presented, which uses the LHeC characteristics serving as a development facility for the design and operation of the LHeC. An updated detector design is presented corresponding to the acceptance, resolution, and calibration goals that arise from the Higgs and parton-density-function physics programmes. This paper also presents novel results for the Future Circular Collider in electron–hadron (FCC-eh) mode, which utilises the same ERL technology to further extend the reach of DIS to even higher centre-of-mass energies.

We carry out a study in the approach of a dimension-8 effective field theory on the anomalous quartic $WW\gamma\gamma$ couplings that arise from the process $pp \to W\gamma\gamma$ at the Future Circular Collider-hadron hadron (FCC-hh). The process is sensitive to the $WW\gamma\gamma$ vertex and future projections on the anomalous $f_ {M,i}/\Lambda^4$ and $ f_ {T,j}/\Lambda^4$ couplings can be put by measurements of $W\gamma\gamma$ production. We illustrate the physics opportunities and reach of the FCC-hh operating for a high integrated luminosity scenario of ${\cal L}=1, 5, 10, 30$ ${\rm ab}^{-1}$ of proton-proton collisions at a center-of-mass energy of $\sqrt{s}=100$ TeV and systematic uncertainties of $\delta_{sys}=0\%, 3\%, 5\%, 10\%$. Production cross-sections of the signal and the sensitivity constraints on the anomalous $f_ {M,i}/\Lambda^4$ and $ f_ {T,j}/\Lambda^4$ couplings at $95\%$ C.L. are identified through the leptonic and hadronic decay modes of the $W$-boson. The FCC-hh sensitivity on these anomalous couplings are expected might reach up to the order of magnitude ${\cal O}(10^{-4}-10^1)$. These sensitivity perspectives indicate that the $pp \to W\gamma\gamma$ channel at the FCC-hh has a greater potential to research for the anomalous quartic $WW\gamma\gamma$ couplings and to research for new physics than present colliders.

In this paper, a study is carried out on the $$e^-p \rightarrow e^-\gamma ^* p \rightarrow p W^-\gamma \nu _e$$ e - p → e - γ ∗ p → p W - γ ν e production to probe quartic $$W^+W^-\gamma \gamma $$ W + W - γ γ couplings at the Large Hadron electron Collider (LHeC) with $$\sqrt{s}= 1.30, 1.98\,\hbox {TeV}$$ s = 1.30 , 1.98 TeV and at the Future Circular Collider-hadron electron (FCC-he) with $$\sqrt{s}= 3.46, 5.29\,\hbox {TeV}$$ 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 $$e^-p$$ e - p colliders, it is possible to obtain sensitivity measures at $$95\%$$ 95 % C.L. on the anomalous $$f_ {M,i}/\Lambda ^4$$ f M , i / Λ 4 and $$ f_ {T,j}/\Lambda ^4$$ f T , j / Λ 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 $$e^-p \rightarrow e^-\gamma ^* p \rightarrow p W^-\gamma \nu _e $$ e - p → e - γ ∗ p → p W - γ ν e in $$e^-p$$ e - p collisions offers a window for study the quartic $$W^+W^-\gamma \gamma $$ W + W - γ γ electroweak bosons couplings at the LHeC and the FCC-he, which provides a much cleaner collision environment than the LHC.
