Proton form factor at large momentum transfer

 

The asymptotic of nucleon form factor at large Q can be computed in QCD using factorization theorem. However, present data do not agree with these predictions. We are going to discuss possible solution of this problem and suggest the new factorization theorem which includes additional, the so-called soft rescattering contribution associated with Feynman mechanism. Possible phenomenological issues will be discussed.
