NOTE ON THE TWO INEQUIVALENT SPIN 1/2 BARYON FIELD OPERATORS

Abstract: (Springer)
There are two inequivalent spin 1/2 local baryon field operators that can be constructed from 3 quarks. A priori theJP=1/2+ baryons can couple to any linear combination of these operators. We show however that the coupling of the 1/2+ baryons to these operators is determined by the value of theSU(3) ratio ofF toD type pseudoscalar-baryon couplings. The experimental value of this ratio implies, for example, that the proton couples strongly to (uTCγd)u and weakly to (uTCd)γsu. This is of interest in QCD sum rule applications.- BARYON: COUPLING
