  The pion transition form factor $G(q^2)$ is computed on the entire domain of
spacelike and timelike
  momenta using a quantum field theory continuum approach. In analytical
continuation of the function $G(Q^2)$ we utilized the Gauge Technique with the
quark propagator
  determined from Minkowski space solution of QCD Dyson-Schwinger equations.
The scale is set up by the phenomena of dynamical chiral symmetry breaking,
which is a striking feature of low energy QCD.
