We introduce an improved version of the simulation code FEWZ (Fully Exclusive W and Z Production) for hadron collider production of lepton pairs through the Drell-Yan process at next-to-next-to-leading-order (NNLO) in the strong coupling constant. The program is fully differential in the phase space of leptons and additional hadronic radiation. The new version offers users significantly more options for customization. FEWZ now bins multiple, user-selectable histograms during a single run, and produces parton distribution function (PDF) errors automatically. It also features a signifcantly improved integration routine, and can take advantage of multiple processor cores locally or on the Condor distributed computing system. We illustrate the new features of FEWZ by presenting numerous phenomenological results for LHC physics. We compare NNLO QCD with initial ATLAS and CMS results, and discuss in detail the effects of detector acceptance on the measurement of angular quantities associated with Z-boson production. We address the issue of technical precision in the presence of severe phase-space cuts.

  1. Fermionic Electroweak Two-Loop Corrections to Drell-Yan and Related Processes

    hep-ph 2025-12 conditional novelty 7.0 of 10

    The full NNLO electroweak corrections with closed fermion loops to e+e- → ffbar (and Drell-Yan) were calculated semi-numerically and found to modify NLO cross-sections by about 1%.

  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. Signals of nonrenormalizable Lorentz and CPT violation at the LHC

    hep-ph 2024-12 conditional novelty 6.0 of 10

    New LHC-derived bounds and projected sensitivities are obtained for dimension-five Lorentz- and CPT-violating quark operators through Z-boson exchange in Drell-Yan production.

    hep-ph 2019-12 unverdicted novelty 5.0 of 10

    New CT18 PDFs at NLO and NNLO from global fit to HERA plus LHC jet, Drell-Yan, top-pair and Z data, with Hessian errors, Lagrange-multiplier studies, and alternate sets for data tensions and scale choices.

  6. Search for heavy neutral resonances decaying to tau lepton pairs in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2024-12 accept novelty 4.0 of 10

    Using 138 fb^-1 of 13 TeV proton-proton collisions, CMS finds no tau-pair resonance and sets its strongest limit yet on Z' bosons.

  7. Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions using the ATLAS detector

    hep-ex 2019-08 accept novelty 4.0 of 10

    Using 139 fb^-1 of 13 TeV pp data, ATLAS finds no sign of charginos or sleptons and excludes chargino masses up to 420 GeV (W-mediated) and slepton masses up to 700 GeV for a massless LSP.

  8. Search for supersymmetry in proton-proton collisions at 13 TeV in final states with jets and missing transverse momentum

    hep-ex 2019-08 accept novelty 4.0 of 10

    A 137 fb^-1 CMS search in the jets-plus-missing-momentum final state finds no supersymmetry excess and sets new 95% CL lower limits of up to 2310 GeV on the gluino mass and 1630 GeV on the squark mass.
