Abstract
In this chapter we recast the theory of nonrelativistic scattering and old-fashioned perturbation theory into relativistic, manifestly covariant language. First we reacquaint ourselves with the relativistic kinematics of two-and three-body decays and two-body scattering processes. Next we reformulate the general dynamical scattering problem in terms of a covariant S-matrix and develop general formulae for decay rates and scattering cross sections. Then after examining the composition of covariant interactions and Feynman propagators, we enumerate a set of Feynman rules from which dynamical S-matrix elements can be constructed.
