Mass spectra of single topped mesons and baryons are predicted with the Godfrey-Isgur-Capstick quark model, whose pseudoscalar topponium mass of 343.29 GeV is claimed to match the CMS/ATLAS threshold excess.

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.
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.
QCD sum rules give doubly topped baryon masses of 345-350 GeV, essentially the sums of the constituent quark masses, with no sign of genuine binding.
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.
