ΔΔ dibaryon structure in chiral SU(3) quark model
Abstract
The structure of the ΔΔ dibaryon is studied in terms of the chiral SU(3) quark model. The ground state energy of ΔΔ dibaryon is evaluated by considering both the ΔΔ and CC (hidden color) channels. The parameter-dependence of the ΔΔ dibaryon mass is also investigated. It is shown that the resultant mass of the ΔΔ dibaryon is lower than the threshold of the ΔΔ channel but still higher than that of the ΔNπ channel.
