论文摘要
在本文中，对$ e^-p \至e^-γ^* p \ to p w^+γν_e$生产进行了一项研究，以探测使用10，100 $ {\ rm fb^{-1}} $ e^-p $ collision collisions $ e^-p $ collisions数据的$ w^+w^+w^+γ$耦合。带有$ \ sqrt {s} $ = 3.46，5.29 GEV的大型强子电子对撞机（LHEC）和100，1000 $ {\ rm fb^{ - 1}} $带有$ \ sqrt {s} $ = 3.46，5.29 GEV。在$ W $ -Boson的Leptonic和Hadroonic Decay频道上都确定生产横截面。借助未来$ e^-p $ colliders的数据，可以以$ 95 \％$ c.l.的灵敏度度量获得。在异常的$ f_ {m，i}/λ^4 $和$ f_ {t，i}/λ^4 $耦合，与LHC获得的限制以及文献中报告的其他限制竞争。生产模式$ e^-p \ to e^-γ^* p \ to $ e^-p $ collisisions中的p w^+γν_e$ collisions提供了一个研究窗口的窗口。
In this paper, a study is carried out on the $e^-p \to e^-γ^* p \to p W^+γν_e$ production to probe quartic $W^+W^-γγ$ couplings using 10, 100 ${\rm fb^{-1}}$ of $e^-p$ collisions data at $\sqrt{s}$= 1.30, 1.98 GeV at the Large Hadron electron Collider (LHeC) and 100, 1000 ${\rm fb^{-1}}$ with $\sqrt{s}$= 3.46, 5.29 GeV at the Future Circular Collider-hadron electron (FCC-he). Production cross-sections are determined for both at leptonic and hadronic decay channel 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 $f_ {M,i}/Λ^4$ and $ f_ {T,i}/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 \to e^-γ^* p \to p W^+γν_e $ 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.
