The five-week program “Precision QCD with the Electron Ion Collider” gathered over 70 experts from diverse fields—including theory, experiment, lattice QCD, and AI/ML. The program addressed major scientific and computational challenges essential for maximizing the physics potential of the EIC. Each week concentrated on a specific theme: from precision QCD and parton distributions to small-x physics, AI-driven detector design, and nucleon tomography. The format encouraged both structured presentations and dynamic collaborative sessions, successfully fostering cross-disciplinary dialogue.
Key outcomes of the program included coordinated strategies for integrating lattice results into global fits, refining saturation physics predictions, and leveraging AI in data analysis and simulation. Participants collaborated on advancing techniques for jet substructure, nucleon and nuclear tomography, and the extraction of transverse momentum and generalized parton distributions (TMDs and GPDs). These discussions also emphasized the importance of quantifying theoretical uncertainties and benchmarking existing tools against one another. One of the most tangible outcomes of the program will be a comprehensive, multi-part document—roughly 10 pages per week—summarizing the current state of each topic, identifying key open questions, and offering coordinated strategies for future work. This document, planned for publication in a peer-reviewed journal, is intended to serve as a valuable resource for researchers across the EIC community and beyond.
