Investigations on the I(JP) = 0(3+) hidden color hexaquark states

Regular Article - Theoretical Physics

Abstract.

Here we investigate the energies of hidden color hexaquark states with quantum numbers \(I(J^{p})=0(3^{+})\) within the framework of the constituent quark model. The hyperfine interaction between quarks is taken to be the instanton-induced interaction, and mixing between different hexaquark configurations caused by hyperfine interaction between quarks is considered. Numerical results show that energies of several obtained hexaquark states are very close to the mass of the experimentally observed \( d^{\ast}\) resonance, it indicates that these states may be the dominant components of \( d^{\ast}\) baryon resonance, if \( d^{\ast}\) is a genuine hexaquark dominated baryon state.
