论文摘要
我们探讨了大型强子电子碰撞器（LHEC）和未来的圆形撞机 - 哈德隆电子（FCC-HE）的物理预期灵敏度，以搜索与光子相关的单个$ W $ boson生产中的异常的四分之一$WWγγ$耦合。我们通过子进程$γ^* q \ towγq'$研究了$ ep \ to e^-γ^* p \ toewγq'x$。假定LHEC的质量中心能量和发光度为$ \ sqrt {s} = 1.30，1.98 $ tev，$ {\ cal l} = 10-100 $ $ $ $ {\ rm fb^{ - 1}} $ l} = 100-1000 $ $ {\ rm fb^{ - 1}} $。借助这些能量和亮度，我们估计异常的四分之一$WWγγ$耦合的界限为$ 95 \％$ c.l.，这可以比Atlas和CMS协作的实验限制报告更为严格。
We explore the physics expected sensitivity at the Large Hadron electron Collider (LHeC) and the Future Circular Collider-hadron electron (FCC-he) to search for the anomalous quartic $WWγγ$ couplings in single $W$-boson production in association with a photon. We study the process $ep \to e^-γ^* p \to eWγq'X$ via the subprocess $γ^* q \to Wγq'$. The center-of-mass energies and luminosities of the LHeC are assumed to be $\sqrt{s}=1.30, 1.98$ TeV, ${\cal L}=10-100$ ${\rm fb^{-1} }$ and for the FCC-he $\sqrt{s}=3.46, 5.29$ TeV and ${\cal L}=100-1000$ ${\rm fb^{-1} }$. With these energies and luminosities, we estimate bounds on the anomalous quartic $WWγγ$ couplings at $95\%$ C.L., which can be an order of magnitude stringent than the experimental limits report by ATLAS and CMS Collaborations at the LHC.
