Speaker
Description
In this talk, we will summarize the goals of the workshop held at Stony Brook University (CFNS) in January 2025, which focused on advancing our understanding of cold nuclear matter (CNM) effects in hadron-nucleus (h+A) collisions. We will explore the challenges of applying perturbative Quantum Chromodynamics (pQCD) to h+A collisions, particularly the complexities arising from CNM effects such as nuclear parton distribution functions (nPDFs), medium-induced gluon radiation, and gluon saturation. The workshop aimed to develop a universal theoretical framework for interpreting experimental data across different collision systems and to highlight the potential of future Electron-Ion Collider (EIC) data. This talk will summarize the key outcomes of the workshop, including the identification of unresolved CNM questions and the definition of the most suitable observables to address them.
