Electromagnetic form-factors of hadrons at large Q2 and effects of confinement
Description
The importance of the nonperturbative effects for the behaviour of electromagnetic form factors of hadrons at large Q2 is emphasized. In the framework of the topological expansion and the colour tube model it is demonstrated, that the dependence of form factors on Q2 is determined by the intercepts of Regge-trajectories. The perturbation theory is used in order to take into account the effects connected to the hard gluon emission. Good description of the magnetic form-factor of nucleon is obtained
