Description
Recently the author proposed that the forces between quarks of two of the colors in the colored-quark model are of shorter range than forces involving quarks of the third color, and showed that if this color-symmetry breaking mechanism is strong, the favored baryon SU(6) representations and parities are 56+ and 70-, in agreement with experimental indications. In this paper it is shown that this prediction also results if the symmetry breaking is small, in which case the sign of the symmetry breaking is irrelevant. The author discusses a possible experimental way to test the validity of the mechanism and measure the approximate size of the symmetry breaking. A useful list of orthonormal quark-model wave functions of specific energies and symmetries is given
