    • Abstract


      The relevance of the recent experimental observation of possible bound and resonant states in$$N\bar N$$ scattering to the Goldberger-Treiman (GT) relation is examined. It is pointed out that anS-wave resonance in$$N\bar N$$ scattering goes a long way towards accounting for the corrections to the GT relations. Values of the mass and width of the resonance capable of giving a reasonable fit for the GT relation are presented.
