摘要：

Isospin and chiral-symmetry breaking due to an ε3u3 Hamiltonian are studied in connection with induced second-class vector currents. In the case of neutron β decay it is found that the induced second-class coefficient is an order of magnitude larger than expected on naive grounds. Predictions for induced effects in -→Λ β decay, τ→δντ, and π→eνγ are also presented. © 1979 The American Physical Society.
