abstract

We compute the total cross section for $t\bar{t}t\bar{t}$ production at next-to-leading logarithmic (NLL$^{\prime}$) accuracy. This is the first time resummation is performed for a hadron-collider process with four colored particles in the final state. The calculation is matched to the next-to-leading order strong and electroweak corrections. The NLL$^{\prime}$ corrections enhance the total production rate by 26\%. The size of the theoretical error due to scale variation is reduced by close to a factor of two, bringing the theoretical error significantly below the current experimental uncertainty of the measurement.

Discussion (0). Continue with ORCID to comment.

  1. The inseparable three and four tops

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Full-NLO predictions for tttW production, combined with tttt through a new window-removal prescription, give a joint inclusive rate more than 10% above the on-shell four-top prediction.

  2. Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data

    hep-ph 2025-07 conditional novelty 6.0 of 10

    A combined fit of LHC and LEP data constrains the five four-heavy-quark Wilson coefficients, and shows that gamma5-scheme choices can shift the resulting bounds.

  3. Triple top baryon $\Omega_{ttt}$

    hep-ph 2025-08 conditional novelty 5.0 of 10

    The triple-top baryon Ωttt is predicted to have mass 513.58 GeV, binding energy 4.13 GeV, and a dominant W+W+W+bbb decay, with production cross sections too small to observe at near-future colliders.

    hep-ex 2025-07 reject novelty 4.0 of 10

    A hybrid GNN with a six-qubit circuit and a jet-multiplicity loss is claimed to improve classification of fully hadronic ttttW events over BDT and XGBoost in Monte Carlo, but the reported significance is inconsistent ...
