of the confinement part of the quark-quark interaction potential. It is shownthat for the case of heavy quarks the results practically do not depend on the value of the mixing parameterx. As to the case of light quarks, the solutions of the Salpeter equation exist only if 0.5 x 1, but the mass spectrum does not depend very much on the values ofx out of this interval. |
