A self-consistent N/D calculation of the rho meson using the Veneziano model

Includes bibliographical references (pages 35)A self-consistent calculation for the rho meson mass and width is performed. The Veneziano model is used to calculate a partial-wave amplitude for pionpion scattering with isospin I=l and angular momentum R =1. The left hand cut discontinuity is obtained for this partial wave and used as input to the Frye-Warnock N/D equations. From the N/D equations, a new partial-wave amplitude satisfying unitarity is determined" The absorption factor, lj(s), is adjusted so that the output p resonance from the new partial wave is consistent with experimental values. By varying parameters associated with the right and left hand cuts, the relative significance of the two cuts is examined. A physical interpretation is also given to the values of the absorption factor which produced the best output. Finally; an avenue for further investigation is suggested
