Role of the rho meson in the nonmesonic hypernuclear decay Parreño García, Assumpta Ramos Gómez, Àngels Bennhold, Cornelius Mesons (Física nuclear) Interaccions febles (Física nuclear) Estructura nuclear Hiperons Mesons Weak interactions (Nuclear physics) Hyperons Nuclear structure The ρ -meson contribution to the Λ N → NN process is studied in the nonmesonic decay of hypernuclei. It is found that the central potential of the ρ exchange is larger than its tensor part and, therefore, must be included. This is in contrast to the π -exchange term which is dominated by the tensor interaction. 2010-01-28T16:22:38Z 2010-01-28T16:22:38Z 1995 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0556-2813 https://hdl.handle.net/2445/10964 112195 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevC.52.R1768 Physical Review C, 1995, vol. 52, núm. 4, p. 1768-1772 http://dx.doi.org/10.1103/PhysRevC.52.R1768 (c) The American Physical Society, 1995 http://dx.doi.org/10.1103/PhysRevC.52.R1768 info:eu-repo/semantics/openAccess 5 p. application/pdf The American Physical Society Articles publicats en revistes (Física Quàntica i Astrofísica)
