rho-meson intermediate states in. pi. -nucleon scattering

Journal Article · · Phys. Rev., C; (United States)
Modifications of the Chew-Low theory caused by the inclusion of rho-nucleon intermediate states are examined. Although this effect changes the form factors necessary to reproduce the (3,3) resonance, no significant change in the resulting phase shifts is obtained. The use of rho-nucleon intermediate states does not eliminate the ''ghost state'' pole in those spin-isospin channels for which the driving term is repulsive.
