ON THE RELATIVISTIC SPIN STRUCTURE OF THE PROTON

We show that it is possible to construct a relativistic nucleon-like o bject within the framework of quantum chromodynamics (QCD). The object corresponds to a system of three minimally correlated, relativistic q uarks in the asymptotically free region. The key to the construction i s the helicity formalism, by which the system can be endowed with well -defined total angular momentum. By using a specific composite boost o f the constituents and the system ro relativistic velocities, we find an effect like Thomas precession. When we calculate the electric form factor of this object, we can extract a non-negligible contribution to the charge radius of such an object.
