Effective Lagrangian with U(1) axial anomaly. II

Technical Report ·
OSTI ID:5838501
;
Properties of the effective Lagrangian obeying anomalous U(3) x U(3) current algebra constraints are discussed. Analytic formulae are deduced for the current interpolating constants F/sub ab/, the topological constant C (governing the strength of coupling of the topological charge to the physical meson spectrum) and the wave function renormalization matrix (..sqrt..Z)/sub ab/. Numerical evaluations of F/sub ab/, C and the gluon content of the eta and eta' are obtained. Strong CP violation deltaL/sub CP/ produced by the theta vacuum is derived, and deltaL/sub CP/ is expressed in terms of physical meson fields.
