Pion Form Factor: Transition From Soft To Hard QCD
Abstract
We have reexamined the elastic pion form factor over a broad range of momentum transfers with the mass evolution from current quark to constituent quark being taken into account. We have also studied the effect of Sudakov form factors, of anomalous quark magnetic moments and of alternative soft wave functions. Our calculation shows a power-law falloff from the present experimental values to near-asymptotic values in the few GeV2 range.
