    Understanding gluon saturation at small $x$ is a central question in high-energy nuclear physics, with deep implications for the non-linear regime of QCD. This talk presents an overview of recent experimental efforts aimed at uncovering signatures of gluon saturation, with a focus on two-particle azimuthal correlations in p+p, p+A, and d+A collisions. Despite theoretical predictions from the...

  11. 6. A Neural-Network Extraction of Unpolarized Transverse-Momentum Distributions from Drell-Yan data
    Chiara Bissolotti (Argonne National Laboratory)
    23/06/2025, 15:45

    We present the first proof of concept extraction using neural networks (NNs) of the unpolarised transverse-momentum distributions (TMDs) at next-to-next-to-next-to- leading logarithmic (N3LL) accuracy. By offering a more flexible and adaptable approach, NNs overcome some of the limitations of traditional functional forms, providing a better description of data. This work focuses exclusively on...

  14. 29. nCTEQ25: Overview and Preliminary Results
    Peter Risse (Southern Methodist University)
    23/06/2025, 17:00

    We discuss the preliminary results of the new global nCTEQ25 nuclear PDF analysis, combining a number of our previous analyses into one consistent framework with updates to the underlying theoretical treatment as well as the addition of new available data. In particular, the nCTEQ24 global release will be the first nCTEQ release containing neutrino DIS scattering data in a consistent manner...
