abstract

The existence of full heavy dibaryons $\Omega_{ccc}\Omega_{bbb}$, $\Omega_{ccc}\Omega_{ccc}$ and $\Omega_{bbb}\Omega_{bbb}$ with $J=0,~1,~2,~3$ and $P=\pm1$ are investigated in the framework of a constituent quark model. The dibaryon composed of six $c$ or $b$ quarks with $J^{P}=0^{+}$ is possible to be bound, while the dibaryon with the $cccbbb$ configuration is difficult to form any bound state. We also study the interaction between two full heavy baryons, and the effective potentials, suggesting the existence of dibaryons $\Omega_{ccc}\Omega_{ccc}$ and $\Omega_{bbb}\Omega_{bbb}$, and the absence of binding for $\Omega_{ccc}\Omega_{bbb}$ system. Besides, the calculation of the low-energy scattering phase shifts of the $\Omega_{ccc}\Omega_{ccc}$ and $\Omega_{bbb}\Omega_{bbb}$, as well as the scattering length also confirm the existence of stable full heavy dibaryons $\Omega_{ccc}\Omega_{ccc}$ and $\Omega_{bbb}\Omega_{bbb}$.

  1. On $\Omega_{3c}NN$ and $\Omega_{3c} \Omega_{3c} N$ systems with HAL QCD potentials

    nucl-th 2025-09 conditional novelty 6.0 of 10

    Ω3cNN and Ω3cΩ3cN are found unbound in S-wave Faddeev calculations with HAL QCD potentials, with only fragile near-threshold resonance estimates for Ω3cnp.

  2. Lattice QCD Study of Positive Parity Dibaryons with Maximal Charm and Strangeness

    hep-lat 2025-07 conditional novelty 6.0 of 10

    Lattice QCD finds the Omega_ccc-Omega_ccc dibaryon likely bound by about 45 MeV in the spin-0 channel, Omega-Omega near threshold, and both spin-2 systems unbound.

  3. Could $\bar{\Lambda}_c$ and $\Lambda_c$ form bound hadronic molecule with explicit $P-wave$ ?

    hep-ph 2026-07 conditional novelty 5.0 of 10

    P-wave Λ̄cΛc dibaryon states with J^PC = 0^-± and 1^-± are extracted at ~5.7–5.8 GeV, about 0.9 GeV above their constituent thresholds, so they are unlikely to be bound molecules.
