CALCULATION OF HADRON FORM-FACTORS FROM EUCLIDEAN DYSON-SCHWINGER EQUATIONS

We apply Euclidean time methods to phenomenological Dyson-Schwinger mo dels of hadrons. By performing a Fourier transform of the momentum spa ce correlation function to Euclidean time and by taking the large Eucl idean time limit, we project onto the lightest on-mass-shell hadron fo r given quantum numbers. The procedure, which actually resembles latti ce gauge theory methods, allows the extraction of moments of structure functions, moments of light-cone wave functions, and form factors wit hout nd hoc extrapolations to the on-mass-shell points. We demonstrate the practicality of the procedure with the example of the pion form f actor.
