Doubly heavy spin--1/2 baryon spectrum in QCD
read the original abstract
We calculate the mass and residue of the heavy spin--1/2 baryons containing two heavy b or c quarks in the framework of QCD sum rules. We use the most general form of the interpolating current in its symmetric and anti-symmetric forms with respect to the exchange of heavy quarks, to calculate the two-point correlation functions describing the baryons under consideration. A comparison of the obtained results with existing predictions from various approaches is also made.

Phenomenology of Hypothetical Single-Top Hadronic States
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 bin...

Light cone QCD sum rules study of the rare radiative $\Xi^{*}_{bb}\to\Xi_b\gamma$ decay
Light cone QCD sum rules produce the form factors T1V(q²=0), T2V(q²=0), T1A(q²=0), T2A(q²=0) for Ξ*bb → Ξb γ, from which the decay width is calculated.

Masses of Purely Top-Quark Bound States: Toponium and the Triply-Top Baryon
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.

Comprehensive Mass Predictions: From Triply Heavy Baryons to Pentaquarks
Machine learning models trained on known hadron data and an extended Gürsey-Radicati mass formula predict masses for triply heavy baryons and numerous pentaquark states, agreeing with available data and forecasting un...
