Unitary Symmetry and the Leptonic Decays of Hadrons

Conference paper
Part of the Few-Body Systems book series (FEWBODY, volume 1/1965)


The structure of the weak currents that appear in the leptonic decays is discussed in the light of unitary symmetry. The known leptonic interaction modes imply the inclusion of more currents than the ones derived from gauge invariance of the octet model. It is therefore suggested that the weak currents emerge from a higher symmetry scheme. The vector part of the interaction is obtained by CVC arguments and the axial-vector part by a Groldberger-Treiman approach. The fit with the experimental situation is discussed.
