本文详述电弱工作组为2026年ESPPU物理简报书评估理论不确定性与对撞机输入，旨在提升结果可复现性与可扩展性。
AI 中文摘要
2025-2026年欧洲粒子物理战略更新再次强调了对未来对撞机项目进行定量稳健比较的重要性。在此背景下，物理筹备组的电弱物理工作组（PPG EW WG）对不同设施在希格斯玻色子、电弱和顶夸克观测量上的预期灵敏度进行了全面评估，特别关注了理论不确定性的不同情景。这些研究总结在《物理简报书》中。本文档旨在：（a）更详细地说明PPG EW WG内部进行的理论不确定性评估，（b）记录电弱和标准模型有效场论（SMEFT）拟合中使用的对撞机特定输入，并讨论为协调各项目之间假设所需的任何修改。通过呈现详细的理论不确定性处理以及明确的对撞机输入和假设，这项工作旨在提高《物理简报书》中呈现结果的可复现性和未来可扩展性。
英文摘要
The 2025-2026 update of the European Strategy for Particle Physics placed renewed emphasis on quantitatively robust comparisons between future collider projects. Within this context, the Electroweak physics working group of the Physics Preparatory Group (PPG EW WG) carried out a comprehensive assessment of the projected sensitivities of different facilities to Higgs boson, electroweak and top-quark observables, with particular attention on different scenarios of theoretical uncertainties. These studies are summarized in the Physics Briefing Book. The aim of this document is to (a) provide a more detailed account of the evaluation of theoretical uncertainties, which was undertaken within the PPG EW WG, and (b) document the collider-specific inputs used in the electroweak and Standard Model effective field theory (SMEFT) fits and discuss any needed modifications in order to harmonize assumptions between projects. In presenting the detailed theoretical uncertainty treatment and the explicit collider inputs and assumptions, this work aims to improve the reproducibility and future extensibility of the results presented in the Physics Briefing Book.
