TO THE DESCRIPTION OF HADRON MASS-SPECTRUM IN THE NONRELATIVISTIC QUARK POTENTIAL MODEL

The comparison of different confinement models of hadrons in non-relativistic quark potential model with the use of hyperspherical functions is carried out in the present work. Numerical values of the masses of non-strange (the lightest) hadrons belonging to the meson octet and baryon decuplet are obtained in this model. The best values of masses are obtained with the potential which incorporates the quasi-relativistic one-gluon exchange and the confinement term Ar(n) with n = 2/3. The natural appearance of the Yukawa-type potential in this model is also discussed.
