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.

abstract
In recent years there has been tremendous progress in the investigation of bound systems of quarks with multiplicities beyond the more usual two- and three-quark systems. Experimental and theoretical progress has been made in the four-, five- and even six-quark sectors. In this paper, we review the possible lightest six-quark states using a simple ansatz based on SU(3) symmetry and evaluate the most promising decay branches. The work will be useful to help focus future experimental searches in this six-quark sector.

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