Theoretical Aspects of the Pion-Pion Interaction

Abstract

We give a brief review of the theoretical description of low energy pion-pion scattering by the combined use of Chiral Perturbation Theory and Roy equations, an update of the Regge parametrization of $\pi \pi$ cross sections at high energies, and a short discussion of the scalar radius of the pion.
