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.
Toponium strengthens the spin-singlet component in top-quark pairs, substantially enhancing entanglement and enabling observable quantum steering at 10 sigma and Bell nonlocality at 9 sigma near threshold with current LHC data.
QCD sum-rule calculations give negative binding energies for toponium states consistent with near-threshold experimental signals and a central mass for the triply-top baryon slightly above three times the top-quark mass.
Phenomenological analysis using NRQCD Green's functions and reweighting shows toponium signals may be detectable in single-leptonic final states with LHC Run 2 data.
Updated non-relativistic Green's function formalism for ttbar threshold production gives a below-threshold cross section of order 6.5 pb matching recent LHC excess observations.
ATLAS data on eμ invariant mass and angle distributions in 13 TeV collisions are better described by ttbar models that include color-singlet quasi-bound states near threshold, with fits showing over 3 sigma evidence and a cross-section matching dedicated threshold studies.
QCD sum-rule calculations yield single-top baryon and meson masses near the top-quark mass, with a few channels slightly below the naive quark-sum threshold.
Near-threshold top-quark pair production cross section at 13 TeV LHC is 11.67 pb with +1.43/-1.47 pb uncertainty, including NRQCD Green's function effects and comparison to POWHEG-BOX.
