- (10).The limits of integration in the sum rules are purposely left unspecified, because we expect the contribution toF 2 from the unphysical spacelike states, which seems to be unavoidable in the Dashen-Gell-Mann program (ref.(7)).. The presence of spacelike states in the deep inelastic electron-nucleon scattering will be felt in the unphysical region −∞<σ≤0. (The physical region is 0<σ≤1.) A closer examination of certain resonance models (ref. (4)) indicates that the functionF 2 will, in all likelihood, be very small (but not altogether zero) in this region.MathSciNetADSCrossRefGoogle Scholar
