“…For a J = 3/2 state (I = 1 or I = 0), the nn and cn interactions are both attractive, which is obvious from Eq. ( 13) or (24), and the width of this state should be relatively narrower. From masses or effective interactions, S-wave Ξ cc D * and Ξ * cc D decay channels are both opened.…”

“…Up to now, theoretical studies have given the masses of the conventional QQQ baryons in various approaches, although there is still no experimental evidence about them. According to these calculations, the mass of the ground Ω ccc baryon, for example, is in the range of 4.6∼5.0 GeV [4,[24][25][26][27]. If an additional quark-antiquark pair surrounds the heavy color source, there is a possibility that the system has a little higher mass and it looks like an excited Ω ccc state.…”

We discuss the mass splittings for the S-wave triply heavy pentaquark states with the QQQq q (Q = b, c; q = u, d, s) configuration which is a mirror structure of Q Qqqq. The latter configuration is related with the nature of Pc(4380) observed by the LHCb Collaboration. The considered pentaquark masses are estimated with a simple method. One finds that such states are probably not narrow even if they do exist. This leaves room for molecule interpretation for a state around the low-lying threshold of a doubly heavy baryon and a heavy-light meson, e.g. ΞccD, if it were observed. As a by product, we conjecture that upper limits for the masses of the conventional triply heavy baryons can be determined by the masses of the conventional doubly heavy baryons.1 Ref. [28] presents a study of the triply heavy pentaquarks with the QQ Qqq configuration.

Inspired by the discovery of the doubly-charmed and doubly-charged Ξ ++ cc baryon, in this present work, we investigate spin-1/2 and spin-3/2 mass spectra and magnetic moments of ccu baryon in quark-diquark model with a nonrelativistic potential. In the quark-diquark picture, the three-body problem of the ccu baryon is reduced to the two-body bound state problem. We obtained ground and radially excited mass spectra and magnetic moments of the ground state. Ground state mass spectra agree well with the results in the literature, especially with lattice QCD computations. Predictions for the magnetic moment are compatible with the literature. According to our results, cu diquark clustering in the Ξ ++ cc baryon is more favorable than the cc diquark clustering.

“…Calculating QQq in a given quark model is rather straightforward, and there are several interesting studies, e.g., [4,5,6]. In the wave function of the first levels, one observes a hierarchy of the average separations, r(QQ) r(Qq), which can be interpreted as a spontaneous or dynamical diquark clustering.…”

We review the physics of doubly-heavy baryons QQq and tetraquarks QQq q. For the latter, the stability is reached for large enough mass ratio M/m, even when spin forces and color mixing are neglected. It is thus customarily claimed that bbq q in its ground state cannot decay into bq + bq. In some model, ccū d is shown to be stable if color mixing and spin effects are properly taken into account. It is conjectured that some bcq q benefits from favorable adjustments of the gluon tubes in the confinement regime. Some recent studies of pentaquarks and hexaquarks are also summarized.
