On the Partical Conservation of the U(1) Current

(Received June 2, 1981)

Abstract:

Recently proposed partial conservation of the U(1) current (PCU1C) is applied to estimate the decay rates of various OZI forbidden processes. The results obtained are in good agreement with experiments and thus indicate the important role played by the U(1) axial-vector anomaly in these decay processes. Octet Jp = (1/2)+ baryons are next introduced into this scheme and low energy theorems related to the θ dependence of the matrix elements are investigated. Physical consequences of non-zero θ (strong CP-violation) are also discussed with the help of the PCU1C. The results are used to give the bound on θ.
