Variation of mixing angles and masses withq2in the standard six-quark model

The variation of mixing angles and masses with $q^2$ in the standard six-quark model is given in terms of a set of coupled differential equations. It is shown that to lowest order, these equations do not depend on the SU(2) gauge coupling, and, in the case of the mixing angles, not even on the U(1) gauge coupling. Experimental implications are briefly discussed.
