There are very few parameters in this approach reproducing the decay properties of almost the complete Rosenfeld table for baryon resonances.

In particular, the theory is able to reproduce the experimentally observed double pole formula for G P E =G P M /μ _P_=G n M /μ n and \(G_E^n = \frac{t}{{4m^2 }}G_M^n \).

  5. -: Phys. Rev. Letters 18, 1027 (1967). One simply assumes the pseudoscalar to transform as an octet operator under SU (3) and uses experimental masses. The mass splitting cause SU (3) breaking in the form factors. Only the unphysical transitions at rest are SU (3) symmetric.

  7. For simplicity we shall assume isospin invariance of the theory. The electromagnetic breaking effects could be included in this theory in quite the same way as the effect of the medium strong interactions on the strangeness changing currents which we shall focus our attention on. The strangeness changing currents will clearly not be conserved.
