Dispersion relations
The analytics of dispersion relations are analyzed to show that a slight change in an analytic function on some interval of the real axis can change completely its analytic properties. Some restricted consequences of microscopic causality in field theory are considered in connection with the propagation of particles. In two-particle scattering the amplitude is expressed for a meson scattered by a nucleon and the analytic properties of the scattering amplitude are given. The scattering of massless particles (photons), pi u mesons, and nucleons is considered as an application of dispersion relations.
