The weak transition operator for the N → N N Λ reaction is identical to a previously developed weak strangeness-changing transition potential Λ → N NN that describes the nonmesonic decay of hypernuclei. The initial NN and final YN state interaction has been included by using realistic baryon-baryon forces that describe the available elastic scattering data. The total and differential cross sections as well as the parity-violating asymmetry are studied for the reaction p → n p Λ . These observables are found to be sensitive to the opening of the Σ production channel, the choice of the strong interaction potential, and the structure of the weak transition potential.8 p.application/pdfeng(c) The American Physical Society, 1999Estructura nuclearReaccions nuclearsNuclear structureNuclear reactionsinfo:eu-repo/semantics/article145195info:eu-repo/semantics/openAccess
