Remarks on chiral symmetry breaking with massless fermions

Abstract

In this talk I present recent results on Lorentz covariant correlation functions $⟨q(p_1)\overline{q}(p_2)⟩$ on the cone $p^2=0$. In particular, chiral symmetry breaking terms are constructed which resemble fermionic 2--point functions of 2--D CFT up to a scalar factor.
