abstract

We discuss cross sections for $tW$ production in proton-proton collisions at the LHC and at higher-energy colliders with energies of up to 100 TeV. We find that, remarkably, the soft-gluon corrections are numerically dominant even at very high collider energies. We present results with soft-gluon corrections at approximate NNLO and approximate N$^3$LO matched to complete NLO results. These higher-order corrections are large and need to be included for better theoretical accuracy and smaller scale dependence. Total cross sections as well as top-quark and $W$-boson transverse-momentum and rapidity distributions are presented using various recent sets of parton distribution functions.

  1. Measurements of the electroweak production of a $W$ boson in association with two jets at $\sqrt{s}=13\,\mathrm{TeV}$ with the ATLAS detector

    hep-ex 2026-07 accept novelty 6.0 of 10

    First differential electroweak W+two-jet cross sections at 13 TeV agree with the Standard Model and give competitive constraints on anomalous triple-gauge-boson couplings.

  2. Measurement of the $|V_{cb}|$ element of the CKM matrix in $t\bar{t}$ decays with the ATLAS detector

    hep-ex 2026-03 accept novelty 6.0 of 10

    ATLAS measures |Vcb|=(50 +11/−14)×10^−3 from on-shell W→cb decays in ttbar events, the first such measurement at the weak scale.

  3. Approximate N$^2$LO and N$^3$LO QCD Predictions for $tW$ Production

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Higher-order QCD corrections to top-plus-W production raise the predicted rate by over 10% and give |Vtb|=0.99±0.03.

  4. Search for a Higgs boson produced in association with a charm quark and decaying to a W boson pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2025-08 conditional novelty 6.0 of 10

    The first search for a Higgs boson produced with a charm quark and decaying to a W-boson pair sees no excess, and combined with the diphoton channel limits the Higgs-charm coupling to below 47 times the standard model...

  5. Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt signatures in the ATLAS detector

    hep-ex 2025-08 accept novelty 4.0 of 10

    The ATLAS search finds no evidence of heavy neutral leptons in W boson decays and sets the strongest limits to date on their mixing with electron and muon neutrinos in the 15-30 GeV mass range.
