A Priori Mixed Baryons and Weak Radiative Decays

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 flavor and parity mixings, is studied. An application to weak radiative decays of hyperons is discussed. It is suggested that this scheme may also be present in non-leptonic and rare mode decays as the enhancement phenomenon.
