论文摘要
CERN的拟议的Electron Proton对撞机实验LHEC和FCC-EH是可以在本世纪实现的最高分辨率显微镜，它们将代表一个非常独特的研究机构。我们利用LHEC和FCC-EH的模拟中性和充电的深度弹性散射数据，并检查它们对标准模型（SM）电子较精度物理学的敏感性，例如有效的弱混合角$ \ sin^2θ__{\ sin^2θ_{弱中性耦合。对于弱混合角的运行以及带电电流相互作用中的电动效应，唯一的测量值得高度可行。使用通用$ s $，$ t $和$ u $参数化研究了对超越SM效应的敏感性。该报告总结了先前有关LHEC的研究，并为FCC-EH提供了新的前景。
The proposed electron-proton collider experiments LHeC and FCC-eh at CERN are the highest resolution microscopes that can be realised in the present century and they would represent a really unique research facility. We exploit simulated neutral-current and charged-current deep-inelastic scattering data of the LHeC and the FCC-eh and examine their sensitivity for precision physics in the Electroweak sector of the Standard Model (SM), like the effective weak mixing angle $\sin^2θ_{\textrm{W},\ell}^\textrm{eff}$, or the light-quark weak-neutral-current couplings. Unique measurements are further feasible at high precision for the running of the weak mixing angle, as well as for electroweak effects in charged current interactions. The sensitivity to beyond SM effects is studied using the generic $S$, $T$ and $U$ parameterization. The report summarizes previous studies about the LHeC and presents new prospects for the FCC-eh.
