EXTRAPOLATION TO CUTS AND THE SCATTERING OF ELECTRONS AND POSITRONS

Abstract

The low momentum transfer region of strong interaction processes may be discussed in terms of one-pion-exchange graphs. This success of extrapolation to poles suggests, as an extension, extrapolation to cuts corresponding to low mass intermediate states containing two or more particles. This extrapolation may be performed in the case of electromagnetic interactions, owing to the vanishing photon mass. This leads to a simple approximate formula for the ratio R is identical with (Sigma(-) - Sigma(+))/(Sigma(-) + Sigma(+)) of electron and positron scattering, and to a simple method of determining the charge form factors of intermediate Z nuclei.
