Citación: | European Physical Journal A 31(4): 557-559 (2007) | Resumen: | We study the central part of the ΛN potential by considering the correlated and uncorrelated two-meson exchange besides the ω exchange contribution. The correlated two-meson is evaluated in a chiral unitary approach. We find that a short-range repulsion is generated by the correlated two-meson potential which also produces an attraction in the intermediate distance region. The uncorrelated two-meson exchange produces a sizeable attraction in all cases which is counterbalanced by ω exchange contribution. | Descripción: | 3 pages, 2 figures.-- PACS nrs.: 13.75.Ev, 12.39.Fe.-- ISI Article Identifier: 000245667300037.
