Flavor symmetry breaking, baryons magnetic moments, and low energy phenomenology of hadrons

A priori mixings of eigenstates in physical states are quantum mechanical effects well known in several realms of physics. The possibility that such effects are also present in particle physics, in the form of mixings that break flavor and parity symmetries, is studied. Applications to non-leptonic and weak radiative decays of hyperons are discussed. The results are very encouraging but should be improved by eventually including the W and Z contributions, assumed small (non-enhanced) in this work.
