Collisions and Decays



In the preceding two chapters we studied freely moving particles. However, a complete absence of interactions can hardly be considered realistic, for in general, particles do interact with one another or with external fields. After all, it is precisely through these interactions that the particles are observed. In this chapter, we will develop a practical method for introducing interactions among relativistic quantum fields and for calculating experimentally measurable quantities such as reaction cross-sections and decay rates.
