Absence of strangeness-changing, neutral current effects from the symmetric quark model

It is shown that the symmetric quark model with Bose quarts or as a three-triplet model with perfect SU(3) double prime (i.e. color) symmetry, supplemented by current algebra and pion PCAC provides an alternative to introduction of a rho prime charmed quark for banishing the absolute value of delta S = 2, delta Q = 0 nonleptonic effects to order (Gs). This mechanism is distinguished by the presence of such effects at high energies, to order (Gs) and/or (Gs) (Gt). Semileptonic the absolute value of delta S = 1, delta Q = 0 effects can be simply avoided by coupling the associated Z's to heavy leptons.
