Gauge technique approximation to the pi gamma production and the pion transition form factor
Original language description
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 an 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.
