    "abstract": "The flavor SU(3)_f group symmetry of QCD is systematically considered as the\nheavy c quark limit of SU(4)_f. Within that scheme we argue that the U(1)_A\nanomaly prevents Gell-Mann\u0027s choice for the realization of the su(4)_f (and\nthereby the su(3)_f) algebra for the particular case of the neutral axial\ncurrents. Rather, Weyl\u0027s choice for the SU(4)_f generators has to be used which\nleads to a neutral strong axial current having same structure (up to a constant\nfactor) as the weak one.",
