Can All Hadronic Symmetry Breaking Be Due to Weak Interactions?

We define, in very general terms, a class of theories in which it is possible for all symmetries such as SU(3) and SU(3) @SU(3) to be exact if one turns off all couplings of leptons and hadrons; but nevertheless, one can have ten to twenty percent violations of these symmetries coming about as a direct consequence of extremely weak lepton-hadron couplings. A framework is proposed for discussing these schemes which is independent of specific Lagrangian models and so leaves open the question of whether or not the Goldstone bosons appearing in these schemes are elementary or composite. For pedagogical purposes the last section of this paper is devoted to a brief discussion of a simple Lagrangian model having the various properties set out in our general scheme.
