The Nucleon Wave Function in Light-Front Dynamics
The general spin structure of the relativistic nucleon wave function in the 3q-model is found. It contains 16 spin components, in contrast to 8 ones known previously. The explicitly covariant form of the wave function automatically takes into account the relativistic spin rotations, without introducing any Melosh rotation matrices. It also reduces the calculations to the standard routine of the Dirac matrices and of the trace techniques. The importance of investigating the influence of the extra components on the observables is emphasized.
