    S. Schmid: private communication. The integral in eq. (1) is evaluated by finite-energy sum rule techniques, as discussed, for example, inR. Dolen, D. Horn andC. Schmid: California Institute of Technology Report No. CALT-68-143 (unpublished).Google Scholar

    It may be objected that it is inconsistent to include the possibility of a singular residue while neglecting possible contributions of branch points to asymptotic behavior. We therefore remark that the «π+ω» branch point is the important one for the residue function, whereas the «ρ+P» branch point is the important one for asymptotic behavior. It is possible that the «ρ+P» branch point be quite weak.Google Scholar
