The existence of full heavy dibaryons $Ω_{ccc}Ω_{bbb}$, $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$ with $J=0,~1,~2,~3$ and $P=\pm1$ are investigated in the framework of a constituent quark model.由$ j^{p} = 0^{+} $组成的六个$ c $或$ b $ quarks可以被绑定，而带有$ cccbbb $ configuration的Dibaryon很难形成任何绑定状态。我们还研究了两个完整的重型bary子和有效潜力之间的相互作用，这表明存在dibaryons $ω_{ccc}ω__{ccc} $和$ω_______________________________________________________________________________________________________{ Besides, the calculation of the low-energy scattering phase shifts of the $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$, as well as the scattering length also confirm the existence of stable full heavy dibaryons $Ω_{ccc}Ω_{ccc}$ and $ω__{bbb}ω__{bbb} $。
The existence of full heavy dibaryons $Ω_{ccc}Ω_{bbb}$, $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$ 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 $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$, and the absence of binding for $Ω_{ccc}Ω_{bbb}$ system. Besides, the calculation of the low-energy scattering phase shifts of the $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$, as well as the scattering length also confirm the existence of stable full heavy dibaryons $Ω_{ccc}Ω_{ccc}$ and $Ω_{bbb}Ω_{bbb}$.
