Abstract

As a concrete example of the idea of renormalization, quantum mechanical scattering of particles by a two-dimensional delta-function potential is considered. The renormalization of the scattering cross section is carried out exactly and analytically. The calculation, free from obscuring mathematical details required for realistic field theories, may aid in making the idea of renormalization more accessible.
