    "abstract": "We study the central part of Lambda N and Lambda Lambda potential by\nconsidering the correlated and uncorrelated two-meson exchange besides the\nomega exchange contribution. The correlated two-meson is evaluated in a chiral\nunitary approach. We find that a short range repulsion is generated by the\ncorrelated two-meson potential which also produces an attraction in the\nintermediate distance region. The uncorrelated two-meson exchange produces a\nsizeable attraction in all cases which is counterbalanced by omega exchange\ncontribution.",
