We present a method to simulate toponium formation events at the LHC using the Green's function of non-relativistic QCD in the Coulomb gauge, which governs the momentum distribution of top quarks in the presence of the QCD potential. This Green's function can be employed to re-weight any matrix elements relevant for $t\bar{t}$ production and decay processes where a colour-singlet top-antitop pair is produced in the $S$-wave at threshold. As an example, we study the formation of $\eta_t$ toponium states in the gluon fusion channel at the LHC, combining the re-weighted matrix elements with parton showering.

    ATLAS observes an excess over 8 sigma in ttbar production near threshold, consistent with NRQCD color-singlet S-wave quasi-bound states, with measured cross-section 9.3^{+1.4}_{-1.3} pb.

  3. Renormalon subtracted nonrelativistic QCD for heavy hadron systems

    hep-ph 2026-07 conditional novelty 6.5

    MRS-pNRQCD plus GFMC stabilizes heavy-hadron spectroscopy; NNLO baryon masses undershoot lattice QCD by 125–175 MeV with 1/m_Q scaling, and a critical mass ratio for tetraquark binding is extracted.

  4. Simultaneous extraction of top quark mass, strong coupling, effective mixing angle, and proton PDFs using inclusive DIS and proton-proton collision data

    hep-ph 2026-07 conditional novelty 6.0

    A single xFitter global fit extracts PDFs, alpha_s(mZ), top pole mass, and sin^2 theta_eff simultaneously at NNLO, with NLO NRQCD threshold corrections, yielding m_t=172.59 GeV, alpha_s=0.1179, sin^2 theta_eff=0.23142.

  5. Top-Antitop Production and Decay at Threshold at the LHC in QCD Perturbation Theory

    hep-ph 2026-07 accept novelty 6.0

    All-order threshold-enhanced QCD corrections in three new NLO+PS generators predict a ~10 pb ttbar cross section in the ATLAS threshold bin and reduce the toponium excess to a perturbative QCD effect.

  6. Top-Antitop Production and Decay at Threshold at the LHC in QCD Perturbation Theory

    hep-ph 2026-07 accept novelty 6.0

    NLO+PS generators with resummed Coulomb threshold corrections show that N3LO already captures most of the ATLAS-bin enhancement, finite-width effects are small, and the loosely defined toponium piece is only a few picobarns.

    hep-ph 2026-03 unverdicted novelty 6.0

    The top-quark pole mass is determined to be 172.80 ± 0.26 GeV from a global NNPDF analysis at approximate N³LO QCD including NLO QED, EW, and toponium corrections.

  8. A Determination of the Top Mass from a Global PDF Analysis

    hep-ph 2026-03 conditional novelty 6.0

    A global PDF fit to LHC top-pair cross-sections extracts the top quark pole mass indirectly as m_t = 172.80 ± 0.26 GeV.

  9. Extracting a Toponium Signal at the LHC with Spin and Quantum Information Tools

    hep-ph 2026-02 conditional novelty 6.0

    Spin and quantum-information observables add only marginal statistical power beyond kinematic variables for isolating toponium in near-threshold top-pair events, but improve interpretability.

  10. New physics in toponium's shadow?

    hep-ph 2025-12 conditional novelty 6.0

    Consistently including toponium bound-state effects inside the new-physics amplitude, not just the Standard Model one, reshapes the allowed mass–coupling region for a top-philic pseudoscalar near the top-antitop threshold.

    Toponium's T-matrix poles survive at realistic top width, supporting a quasi-bound-state interpretation despite the spectrum appearing as a single broad peak.
