Various hadron ”radii” that appear in the literature, e.g.”charge”, ”gravitational”, etc, do not have a direct geometric meaning and do not give an idea of the physical size of a hadron. They, however, can be used to estimate the genuine sizes of hadrons. In the framework of the Gribov-Feynman parton scheme we show that at high enough energy a gluon cloud appears beyond the valence core of the nucleon and begins to determine the region of interaction of elastic nucleon-nucleon scattering and the growth of its cross-section.
