A new two-step Gaussian expansion method enables high-precision calculation of fine structure in negative-parity singly heavy baryons via the relativized quark model, reproducing data to <5 MeV average deviation.
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.
Mass spectra of 1F-wave singly heavy baryons computed via Regge trajectory model in quark-diquark configuration with spin-dependent mass shifts.
