FIELD-CURRENT IDENTITY PARTIALLY CONSERVED CURRENTS AND VENEZIANO MODEL

Hard-meson partial conservation of axial-vector current and partial conservation of vector current are imposed upon the Veneziano amplitudes. It is seen that these determine inelastic amplitudes (e.g., A1, etc.) in terms of corresponding elastic amplitudes (e.g.,). Mass formulas for the and meson, equality of many trajectory slopes of either normality, and scattering lengths are obtained, in good agreement with experiment. © 1969 The American Physical Society.
