  1. 21. Partonic distributions from Lattice QCD
    Krzysztof Cichy

    Hadron structure: pdfs, small-x and large-x physics
    Talk

    In this talk, we discuss the recent progress in Lattice QCD extractions of partonic distributions of the nucleon. The focus of the talk are parton distribution functions (PDFs) as well as generalized parton distributions (GPDs), at leading twist and at twist-3. We review theoretical and practical advances in this field and present a selection of results obtained in the last years. Finally, we...

  2. 19. Small- and Large-x resummations in PDF fits
    Marco Bonvini (INFN, Rome 1 Unit)

    Hadron structure: pdfs, small-x and large-x physics
    Talk

    I will review the state-of-the-art determinations of parton distribution functions obtained with the inclusion of large-x and small-x logarithmic resummations in the theoretical predictions, and present future perspectives in this context.

  3. 47. Theory uncertainties from theory nuisance parameters in fixed-order QCD (online)

    Talk

    Precision computations for standard candle processes are a staple of the physics programme at colliders such as the Large Hadron Collider (LHC). The highest precision can be achieved in perturbative computations. In perturbation theory, however, calculations truncated at a fixed order inevitably have inherent theoretical uncertainty. This uncertainty quantifies the contributions from the...

  4. 54. On the origin of the peak of the sound velocity for isospin imbalanced strongly interacting matter

    Hadron structure: pdfs, small-x and large-x physics
    Talk

    We study the properties of a system composed of strongly interacting matter with an isospin imbalance, using as an effective description of QCD the two-flavor Linear Sigma Model with quarks. From the one-loop effective
    potential, including the two light quarks, pions and
    sigma contributions, and enforcing the restrictions imposed by chiral symmetry, we show that the development of an isospin...

  5. 46. Nuclear parton distribution functions
    Michael Klasen
    25/09/2025, 09:25
    Hadron structure: pdfs, small-x and large-x physics
    Talk

    We review the theoretical foundations, methodological approaches and current status of the determination of nuclear parton distribution functions (PDFs). A large variety of measurements in fixed-target and collider experiments provide increasingly precise constraints on various aspects of nuclear PDFs, including shadowing, antishadowing, the EMC effect, Fermi motion, flavour separation,...

  6. 49. Theory and modelling of multi-parton distributions
    Jonathan Richard Gaunt (The University of Manchester (GB))
    25/09/2025, 09:50
    Hadron structure: pdfs, small-x and large-x physics
    Talk

    I will discuss progress in the theoretical treatment and modelling of multi-parton distibutions, focussing on the inclusion of various types of correlations beyond the simple “pocket formula” approach. Such distributions are needed for theoretical predictions of multiple parton scattering cross sections at the LHC. I will focus mainly on the case of double parton distributions, but will also...

    Hadron structure: pdfs, small-x and large-x physics
    Talk

    Hadronization, the non-perturbative process through which quarks become color-neutral hadrons, remains a key challenge in QCD. Complementary insights into this process come from diverse experiments, including Drell-Yan, Heavy-Ion collisions, and Semi-Inclusive Deep-Inelastic Scattering (SIDIS).

    This talk focuses on recent and ongoing SIDIS studies off nuclear targets, a program initiated...
