Beyond the Standard Model

Abstract

These lectures constitute a short course in `Beyond the Standard Model' for students of experimental particle physics. I discuss the general ideas which guide the construction of models of physics beyond the Standard Model. The central principle, the one which most directly motivates the search for new physics, is the search for the mechanism of the spontaneous symmetry breaking observed in the theory of weak interactions. To illustrate models of weak-interaction symmetry breaking, I give a detailed discussion of the idea of supersymmetry and that of new strong interactions at the TeV energy scale. I discuss experiments that will probe the details of these models at future pp and e+e- colliders. [Lectures presented at the 1996 European School of High-Energy Physics.]
