We study the infrared behaviour of tree-level QCD amplitudes and we derive infrared-factorization formulae that are valid at any perturbative order. We explicitly compute all the universal infrared factors that control the singularities in the various soft and/or collinear limits at O(as^2).

  1. A first extraction of gluon TMDs from Higgs data at the LHC

    hep-ph 2026-05 unverdicted novelty 8.0

    First extraction of gluon TMDs from ATLAS and CMS Higgs q_T distributions at 8 and 13 TeV within TMD factorisation at N3LL accuracy.

  2. Factorization of the triple-collinear $q \to qc\bar{c}$ splitting function at first order in opacity

    hep-ph 2026-07 conditional novelty 7.0

    At first order in opacity, the medium-modified q->q c cbar splitting function factorizes into products of q->q g and g->c cbar splitting functions in three strongly ordered collinear limits.

  3. Double-real corrections to color singlet decay in a parton-shower inspired scheme

    hep-ph 2026-06 unverdicted novelty 7.0

    A parton-shower-inspired local subtraction scheme for double-real corrections in color singlet decays is introduced, with finiteness verified for the e+e- to qqbar remainder and phase-space integrals computed analytic...

    hep-ph 2026-04 unverdicted novelty 7.0

    A decomposition splits the most singular dipole term of the N-jettiness soft function into an inclusive soft function and a remainder that is absent at NLO, finite at NNLO, and subtractable at N3LO, enabling NNLO resu...

  5. Energy Correlators of Spinning Sources

    hep-ph 2025-12 conditional novelty 7.0

    Spinning energy correlators classify the full Euler-angle dependence of N-point energy flux, obey generalized Hofman–Maldacena positivity bounds, and their ratios to inclusive correlators in QCD are largely insensitiv...

  6. Dissecting Parton Showers with Multi-Point Energy Correlators

    hep-ph 2026-07 accept novelty 6.0

    Projections of four-point energy correlators cleanly separate spin from kinematic azimuthal correlations inside jets; spin effects are subdominant in accessible LHC kinematics.

  7. Non-abelian soft radiation data for a celestial theory

    hep-th 2025-12 conditional novelty 6.0

    Non-abelian soft-emission data imply that celestial OPE coefficients depend on gluon energy fractions, breaking holomorphic factorization and associativity, while single-soft logarithms can be reabsorbed into the runn...

  8. Low-energy theory of jet processes and PDF factorization

    hep-ph 2025-09 conditional novelty 6.0

    A three-loop Glauber contribution to low-energy soft-collinear matrix elements exactly cancels the collinear factorization-violating terms, so DGLAP running and PDF factorization are consistent with super-leading logarithms.
