Current Algebras and Meson Decays
Abstract
By using quarkalgebra equaltime commutation relations and a smooth poledominated form for the vectorvectoraxialvector vertex in the highenergy limit, one can describe the radiative decays of the vector mesons and the ω>3π decay in excellent agreement with experimental data. It is shown, however, that if we exploit all equations this procedure gives, we get into contradictions. By introducing a nonsmooth amplitude, the contradictions can be eliminated in such a way that the good predictions of the smooth case remain unaltered. The various aspects of the results are discussed.
