Abstract

The mass of the dibaryon having spin, parityJ π = 0+, isospinI = 0 and strangeness—2 is computed using chiral color dielectric model. The bare wave function is constructed as a product of two color-singlet three-quark clusters and then it is properly antisymmetrized by considering appropriate exchange operators for spin, flavor and color. Color magnetic energy due to gluon exchange, meson self energy and energy correction due to center of mass motion are computed. The calculation shows that the mass of the particle is 80 to 160 MeV less than twice λ mass.

  12. The notation used for the dibaryon octet is the same as that of the baryon octet. Thus,MN is the mass of the dibaryon with isospin 1/2, hypercharge 1 and spin 1. It should not be confused with the nucleon mass
