Without proper control of numerical and methodological errors in theoretical predictions at the per mille level it is not possible to study the effect of input parameters in current hadron-collider measurements at the required precision. We present a new version of the parton-level code MCFM that achieves this requirement through its highly-parallelized nature, significant performance improvements and new features. An automatic differential cutoff extrapolation is introduced to assess the cutoff dependence of all results, thus ensuring their reliability and potentially improving fixed-cutoff results by an order of magnitude. The efficient differential study of PDF uncertainties and PDF set differences at NNLO, for multiple PDF sets simultaneously, is achieved by exploiting correlations. We use these improvements to study uncertainties and PDF sensitivity at NNLO, using 371 PDF set members. The work described here permits NNLO studies that were previously prohibitively expensive, and lays the groundwork necessary for a future implementation of NNLO calculations with a jet at Born level in MCFM.

  1. NNLOCAL: completely local subtractions for color-singlet production in hadron collisions

    hep-ph 2024-12 conditional novelty 7.0 of 10

    NNLOCAL is the first public implementation of a completely local analytic NNLO subtraction scheme for hadron collisions, validated on gluon-only Higgs production.

  2. Measurement of differential $t$-channel single top (anti)quark production cross-sections at 13 TeV with the ATLAS detector

    hep-ex 2026-01 accept novelty 6.0 of 10

    First separate differential tq and tbarq t-channel single-top cross-sections at 13 TeV, using the full ATLAS Run 2 sample, agree with NLO/NNLO QCD and set −0.12 < C_Qq^{3,1}/Λ² < 0.12 TeV⁻² at 95% CL.

  3. Constraining non-commutative geometry with W/Z+jet production at the LHC

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Non-commutative spacetime corrections to W/Z+jet production appear at first order in Θ, and ATLAS Z+jet data constrain the non-commutative scale to Λ ≳ 2 TeV.

  4. Recoil-Safe Subtraction, Matching and Merging in e+e- to hadrons

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The Alaric shower is matched to NLO matrix elements and merged to five jets in e+e- to hadrons, with new analytic subtraction terms validated against Catani-Seymour subtraction.

  5. MATRIX HAWAII: PineAPPL interpolation grids with MATRIX

    hep-ph 2025-06 accept novelty 6.0 of 10

    Matrix Hawaii provides a public interface between PineAPPL and MATRIX that generates interpolation grids at NNLO QCD + NLO EW accuracy for a range of LHC processes, with sub-permille interpolation errors.

  6. Quark-universal $U(1)$ breaking scalar at the LHC

    hep-ph 2025-06 conditional novelty 6.0 of 10

    In a quark-universal U(1)_B model, the scalar φ that breaks the symmetry can be discovered first through its diphoton decay, and its rate can explain the 95 GeV diphoton excess.

  7. Automated NLO calculations for asymmetric hadron-hadron collisions in MadGraph5_aMC@NLO

    hep-ph 2025-01 accept novelty 6.0 of 10

    A public extension of MadGraph5_aMC@NLO now computes automated NLO QCD cross sections for asymmetric hadron-hadron collisions, validated against MCFM and JAM.

  8. Probing SU(2) Quark Flavor Asymmetry with W Bosons at RHIC

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    The STAR W+/W- lepton pseudorapidity ratio is nearly insensitive to QCD recoil veto effects and resummation, making it a usable probe of the proton's dbar/ubar asymmetry near x=0.1.
