Re-examination of the πN N N-N N N problem

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

We discuss the dynamical equations for the πN N N-N N N} system. We introduce the Afnan-Blankleider-Avishai-Mizutani equations in a very direct and immediate way, using the diagrammatic method and special properties of the four-body transition operators. The connection between this four-body unitary theory and a more phenomenological model for the3He + π→N N Nprocess, recently developed by the authors, is established.
