Abstract: We apply Euclidean time methods to phenomenological Dyson-Schwinger models of hadrons. By performing a Fourier transform of the momentum space correlation function to Euclidean time and by taking the large Euclidean time limit, we project onto the lightest on-mass-shell hadron for given quantum numbers. The procedure, which actually resembles lattice gauge theory methods, allows the extraction of moments of structure functions, moments of light-cone wave functions, and form factors without ad hoc extrapolations to the on-mass-shell points. We demonstrate the practicality of the procedure with the example of the pion form factor.
