Binding energy of the dihyperon in the quark cluster model
- 1. Tuebingen Univ. (Germany, F.R.). Inst. fuer Theoretische Physik
Description
The dihyperon is described in the non-relativistic quark cluster model. The SU(3) flavor symmetry breaking due to the different quark masses is taken into account not only in the hamiltonian, but also in the quark wave functions. The interaction contains the one-gluon-exchange potential, pseudoscalar-meson exchange between quarks plus an additional phenomenological σ-meson exchange. The mass of the dihyperon is predicated to be (2211±5) MeV, i.e. a binding energy of the dihyperon of(-20±5) MeV below the ΛΛ threshold is found. (orig.)
