A model for space and time-like proton (neutron) form factors

Abstract : Recent experiments on the electromagnetic proton and neutron form factors reveal very peculiar features such as the decreasing of the ratio of electric to magnetic form factor of the proton as function of the transfer momentum squared, in electron proton elastic scattering. A model is suggested to describe the known experimental behavior of nucleon form factors both in space and time-like regions. It implies quarks to be colorless in the region of high intensity chomo-magnetic gluon field inside the nucleon.
