Abstract: (Elsevier)
The non-relativistic cluster model is used to describe the hyperon-nucleon (ΛN, ΣN) and hyperon-hyperon (H-dibaryon) interaction. Including central and tensor parts of the one-gluon exchange, pseudoscalar-meson exchange plus an additional phenomenological σ-meson exchange, a very good fit of the experimental hyperon-nucleon cross-sections is achieved. Applying this model to the H-dibaryon, a bound state with a binding energy of (−15 ± 5) MeV below the ΛΛ threshold is found, i.e. the mass of the H-dibaryon is predicted to be around 2216 MeV.- talk
