2025年EIC-法国研讨会：物理亮点与展望
2025 EIC-France Workshop: Physics Highlights and Perspectives
AI总结：
2025年EIC-法国研讨会聚焦于EIC早期物理计划，探讨了包络散射和夸克onium生产等关键测量，以及长期物理机会，如三维π子结构探索。
摘要：
本文汇总了第二届EIC-法国研讨会的理论贡献和讨论内容，该研讨会于2025年12月1日至3日在Orsay的IJCLab举行。研讨会汇集了法国强子物理社区的成员，回顾了与未来电子离子对撞机（EIC）相关的最新理论发展，并协调了国家在准备其早期物理计划中的努力。报告首先总结了对撞机的初始运行条件和亮度性能，如EIC早期科学矩阵中所述。随后，报告提供了关于包络、半包络、排斥、重味和小x物理的理论报告的简要概述。基于这些讨论，两项测量被确定为特别适合早期EIC运行，并且与法国已建立的专业领域高度契合：包络散射和包络夸克onium生产。这些通道提供了清晰的信号，具有稳健的理论解释性，并直接敏感于基本QCD现象，如胶子饱和、重夸克动力学以及强子和核的小x结构。此外，研讨会还识别了在EIC完成爬坡阶段后能够受益于其全部能力的长期物理机会。这些包括通过Sullivan过程访问π子的三维结构以及更广泛的排除三体最终态计划，这两者代表了探索强子结构和非微扰QCD的高影响途径。共同，报告中总结的要素提供了关于塑造法国社区对EIC物理计划的战略优先事项和科学雄心的连贯概述。
英文摘要：
This document presents a synthesis of the theory contributions and discussions from the 2nd EIC-France Workshop, held at IJCLab (Orsay) on 1-3 December 2025. The workshop brought together members of the French hadron-physics community to review recent theoretical developments relevant to the future Electron-Ion Collider (EIC) and to coordinate national efforts in preparation for its early physics program. The report first summarizes the collider's initial running conditions and luminosity performance, as outlined in the EIC Early Science Matrix. It then provides concise overviews of the theoretical presentations on inclusive, semi-inclusive, exclusive, heavy-flavor, and small-x physics. Based on these discussions, two measurements emerged as especially well suited for early EIC operation and strongly aligned with areas of established French expertise: inclusive diffraction and inclusive quarkonium production. These channels offer clean signatures, robust theoretical interpretability, and direct sensitivity to fundamental QCD phenomena such as gluon saturation, heavy-quark dynamics, and the small-x structure of hadrons and nuclei. In addition, the workshop identified longer-term physics opportunities that will benefit from the full capabilities of the EIC after its ramp-up phase. These include accessing the three-dimensional structure of the pion through the Sullivan process and a broader program of exclusive three-body final states, both of which represent high-impact avenues for exploring hadronic structure and non-perturbative QCD. Together, the elements summarized in this report provide a coherent overview of the strategic priorities and scientific ambitions shaping the French community's contribution to the EIC physics program.
