In the quasilinear Regge trajectory ansatz, some useful linear mass inequalities, quadratic mass inequalities and quadratic mass equalities are derived for mesons and baryons. Based on these relations, mass ranges of some mesons and baryons are given. The masses ofbc and ss belonging to the pseudoscalar, vector and tensor meson multiplets are also extracted. The J P of the baryon Ξ + cc (3520) is assigned to be

In the framework of potential models for heavy quarkonium the mass spectrum for the system (bc) is considered. Spin-dependent splittings, taking into account a change of a constant for effective coulomb interaction between the quarks, and widths of radiative transitions between the (bc) levels are calculated. In the framework of QCD sum rules, masses of the lightest vector B * c and pseudoscalar B c states are estimated, scaling relation for leptonic constants of heavy quarkonia is derived, and the leptonic constant f Bc is evaluated. The B c decays are considered in the framework of both the potential models and the QCD sum rules, where the significance of Coulomb-like corrections is shown. The relations, following from the approximate spin symmetry for the heavy quarks in the heavy quarkonium, are analysed for the form factors of the semileptonic weak exclusive decays of B c . The B c lifetime is evaluated with the account of the corrections to the spectator mechanism of the decay, because of the quark binding into the meson. The total and differential cross sections of the B c production in different interactions are calculated. The analytic expressions for the fragmentational production cross sections of B c are derived. The possibility of the practical B c search in the current and planning experiments at electron-positron and hadron colliders is analysed.

“…The success of the heavy quark effective theory (HQET) [5] in predicting some properties of the heavy-light qQ mesons (B and D) suggests to apply these methods to heavy-light baryons, too. The simplest baryonic systems of this kind are the so-called doubly heavy baryons (qQQ) [1,6,7,8,9,10,11,12]. The two heavy quarks (b or c) compose in this case a bound diquark system in the antitriplet colour state which serves as a localized colour source.…”

Mass spectra of doubly heavy baryons in the relativistic quark model

Mass spectra of baryons consisting of two heavy (b or c) and one light quarks are calculated in the framework of the relativistic quark model. The light quark-heavy diquark structure of the baryon is assumed. Under this assumption the ground and excited states of both the diquark and quark-diquark bound system are considered.The quark-diquark potential is constructed. The light quark is treated completely relativistically, while the expansion in the inverse heavy quark mass is used revealing the close similarity with the mass spectra of B and D mesons. We find that the relativistic treatment of the light quark plays an important role. The level inversion of the p-wave excitations of the light quark in doubly heavy baryons is discussed.
