abstract

We study next-to-leading-power (NLP) threshold corrections in colour-singlet production processes, with particular emphasis on Drell-Yan (DY) and single-Higgs production. We assess the quality of the partonic and hadronic threshold expansions for each process up to NNLO. We determine numerically the NLP leading-logarithmic (LL) resummed contribution in addition to the leading-power next-to-next-to-leading logarithmic (LP NNLL) resummed DY and Higgs cross sections, matched to NNLO. We find that the inclusion of NLP logarithms is numerically more relevant than increasing the precision to N$^3$LL at LP for these processes. We also perform an analytical and numerical comparison of LP NNLL + NLP LL resummation in soft-collinear effective theory and direct QCD, where we achieve excellent analytical and numerical agreement once the NLP LL terms are included in both formalisms. Our results underline the phenomenological importance of understanding the NLP structure of QCD cross sections.

    hep-ph 2026-07 unverdicted novelty 7.0 of 10

    Computes NLO matching of QCD currents to power-suppressed two- and three-particle two-jet operators in SCET up to O(λ²), with endpoint factorization relations shown.

  2. Slepton pair production at next-to-leading power

    hep-ph 2025-10 unverdicted novelty 6.0 of 10

    Evaluates next-to-leading power threshold corrections for slepton pair production and finds them significant compared to leading power NLL terms, with underestimated scale errors for large masses.

  3. Associated $ZH$ production in gluon fusion process at NLO+NLL

    hep-ph 2026-05 unverdicted novelty 5.0 of 10

    NLO+NLL QCD corrections to gluon-fusion ZH production increase the cross-section by ~20% and reduce scale uncertainties from 20% to 12% at LHC energies, combined with Drell-Yan N3LL results.

  4. NLP threshold corrections to W+jet production

    hep-ph 2025-10 unverdicted novelty 5.0 of 10

    Computes helicity-dependent NLP leading logs in W+jet production via spinor shifts and soft quark operators, confirming agreement with a universal NLP structure for massive colourless final states plus jet.
