  1. 79. Transverse momentum-dependent observables from Lattice QCD
    Michael Engelhardt
    10/06/2026, 09:00

    A class of transverse momentum-dependent (TMD) proton observables that can be evaluated within Lattice QCD in a particularly robust fashion are ratios of TMD Mellin moments. These observables are thus particularly well-suited for achieving a controlled, quantitative connection to phenomenology. Lattice QCD studies of such TMD ratios are presented, based on calculations of proton matrix...

  2. 93. Testing the Predictive Power of Lattice QCD for the Collins–Soper Kernel within TMD Factorization
    Mariaelena Boglione (Istituto Nazionale di Fisica Nucleare)

    Modern investigations of hadron structure within TMD factorization require a precise determination of the Collins–Soper (CS) kernel, which governs TMD evolution and encodes nonperturbative dynamics. In this talk, I present a phenomenological analysis of the CS kernel based on recent lattice QCD calculations, aiming to assess their consistency with experimental data. A flexible fitting...

  3. 107. Factorization and resummation for LHC jet processes (with implications for the EIC)
    Matthias Neubert (Johannes Gutenberg University Mainz)
    10/06/2026, 09:55

    Jet cross sections at hadron colliders are sensitive to coherence-violating double logarithmic corrections (often called “super-leading logarithms”) in higher orders of perturbation theory. For both non-global and global jet observables, we discuss the physical origin of these effects and show how they can be resummed. Despite the fact that collinear factorization is violated in these...

  4. 44. Global analysis of Energy–Energy Correlation data: extraction of αₛ and non-perturbative effects
    Lorenzo Rossi (Istituto Nazionale di Fisica Nucleare)
    10/06/2026, 10:20

    In this talk we present a global analysis of Energy–Energy Correlation (EEC) data in electron–positron annihilation. Our theoretical framework combines resummation of logarithmically enhanced contributions up to next-to-next-to-next-to-leading logarithmic (N³LL) accuracy with fixed-order predictions at next-to-next-to-leading order (NNLO).
    This approach enables a precise extraction of the...
