Field-current identity, partially conserved currents, and the Veneziano model

Hard-meson partial conservations of axial-vector and partial conservation of vector current are imposed upon the Veneziano amplitudes. It is seen that these determine inelastic amplitudes (e.g., ππ→πA1, etc.) in terms of corresponding elastic amplitudes (e.g., ππ→ππ). Mass formulas for the κ and δ meson, equality of many trajectory slopes of either normality, and πK scattering lengths are obtained, in good agreement with experiment
