AI中文摘要：
我们探讨了未来多个可能的10 TeV尾场对撞机测量希格斯玻色子电弱耦合的潜力。发现只要能高精度测量或计算光度谱，束流相互作用不会阻碍希格斯耦合的高精度测量。除了正负电子对撞机，还评估了电子电子对撞机或γγ对撞机等替代方案，绕过了尾场对撞机中 positron 加速的挑战。发现γγ对撞机中10 ab⁻¹数据集的灵敏度与μ子对撞机中10 ab⁻¹和正负电子尾场对撞机中1 ab⁻¹定性相似。
英文摘要：
We explore the potential of multiple possible future 10 TeV wakefield colliders to measure electroweak couplings of the Higgs boson. We find that the beam-beam interactions are not an impediment to high precision measurements of the Higgs couplings, provided that the luminosity spectra can be measured or calculated to high accuracy. In addition to $e^+ e^-$ colliders, we also assess the effectiveness of alternatives such as $e^- e^-$ colliders or $γγ$ colliders, which by-pass the positron acceleration challenge for wakefield colliders. We find that a 10 $\text{ab}^{-1}$ dataset at a $γγ$ collider yields qualitatively similar sensitivity to 10 $\text{ab}^{-1}$ at a muon collider and 1 $\text{ab}^{-1}$ at an $e^+e^-$ wakefield collider.
