Chiral Symmetry {it Breaking} in the Light-Cone Representation (M_π² sim μ_q <Ω |bar{psi}psi|Ω > +...)

In this paper I shall discuss the way in which vacuum structure and condensates occur in the light-cone representation. I shall particularly emphasize the mechanism by which the mass squared of a composite such as the pion comes to depend linearly on the bare mass of its Fermion constituents. I shall give details in two dimensions then discuss the case of four dimensions more speculatively.
