• 論文の詳細を見る

• Recently proposed partial conservation of the U(1) current (PCU_1C) 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 J^p=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 PCU_1C. The results are used to give the boumd on θ.
