✦ Synopsis

The relations among differential cross section, polarization and helicity density matrix elements in yN -+ nN and TN --L VN processes are given for the photon-vector-meson analogy model. For example, the differential cross sections of yN + ?rN processes are given in terms of density matrix elements and differential cross sections of nN ---t pN processes, and the relations fit the experimental data fairly well.

A general technique for obtaining dispersion relations in the mass variable is proposed. The method is used in order to translate the low-energy theorems valid for "mathematical pions" of zero four-momentum into physically meaningful expressions for real pions. Our procedure is explicitly applied to
