Description
Several recent papers, using effective QCD chiral Lagrangians, reproduced results obtained with the general QCD parametrization (GP). These include the baryon 8+10 mass formula, the octet magnetic moments and the coincidental nature of the 'perfect' (μp/μn)=-(3/2) ratio. Although we anticipated that the GP covers the case of chiral treatments, the above results explicitly exemplify this fact. Also we show by the GP that, in any model or theory (chiral or nonchiral) reproducing the results of QCD, the Franklin (Coleman-Glashow) sum rule for the octet magnetic moments must be violated
