Abstract
Nonleptonic decays due to a current-current interaction are considered in a nonlinear chiral Lagrangian model with a field-current identity. The apparently attractive possibility of preserving the complete chiral field algebra exactly even after the weak interactions (as well as symmetry-breaking effects for all particles) are included is shown to fail: 3-point vertices for parity-violating baryon B→B′π and K→2π decays vanish.
