Abstract

The mass of the $H$ dibaryon with spin, parity ${J}^{\ensuremath{\pi}}{=0}^{+}$, and isospin $I=0$ is calculated in the framework of the chiral color dielectric model. The wave function of the $H$ dibaryon is expressed as a product of two color-singlet baryon clusters. Thus the quark wave functions within the cluster are antisymmetric. Appropriate operators are then used to antisymmetrize intercluster quark wave functions. The radial part of the quark wave functions are obtained by solving the quark and dielectric field equations of motion obtained in the color dielectric model. The mass of the $H$ dibaryon is computed by including the color magnetic energy as well as the energy due to meson interaction. The recoil correction to the $H$ dibaryon mass is incorporated by Peierls-Yoccoz technique. We find that the mass of the $H$ dibaryon is smaller than the $\ensuremath{\Lambda}\ensuremath{-}\ensuremath{\Lambda}$ threshold by over 100 MeV. The implications of our results on the present day relativistic heavy ion experiments are discussed.
