Spontaneous Breaking of Chiral Flavor Symmetry in QCD

On chiral realizations of confining theories

It is argued that chirality is not necessarily broken in SU( N) colour theories with a chiral flavour symmetry. In this case, massless fermion bound states contributr to anomaly equations, and loop expansions in a 1/ N approach are invalid. As a hint to understanding which option is realized by the theory, we investigate it in two dimensions for very small quark masses. The light spectrum shows a rich structure not obtained in a 1 N expansion. Light flavoured baryons and mesons indicate a partial realization of the chiral symmetry.
