Three-Quark Wave Function of Nucleon in the Quasipotential Approach
Abstract
Description
The structure of the nucleon wave function as a bound system of the constituent quarks was considered in framework of the quasipotential method of description of the bound states with a fixed number of particles.
In the impulse approximation the wave function is reduced to the three-quark component of the vector state in the Fock-momentum space.
Spin structure of the wave function was studied by the decomposition method of the irreducible representations product of inhomogeneous Lorentz group.
Physical distinction of SU(6) symmetric solution is determined by uniqueness of this solution in the nonrelativistic limit.
The effective mass approximation for the relativistic theory was numerically studied, in which dispersion of the average quark momentum is small as compare to a big average quark momentum.
Relativistic generalization of the nonrelativistic three-particle oscillator was proposed.
