Abstract

The existence of full heavy dibaryons Ω_cccΩ_bbb, Ω_cccΩ_ccc and Ω_bbbΩ_bbb with J=0,~1,~2,~3 and P=±1 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_cccΩ_ccc and Ω_bbbΩ_bbb, and the absence of binding for Ω_cccΩ_bbb system. Besides, the calculation of the low-energy scattering phase shifts of the Ω_cccΩ_ccc and Ω_bbbΩ_bbb, as well as the scattering length also confirm the existence of stable full heavy dibaryons Ω_cccΩ_ccc and Ω_bbbΩ_bbb.
