QCD sum rule calculations produce ground-state masses for single-top baryons like Lambda_t and mesons like T_t b-bar, with several central values slightly below constituent quark mass sums suggesting possible weak binding within uncertainties.

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.
