W. Kilian (DESY):

What could there be besides supersymmetry?

Abstract:

Despite the fact that supersymmetry is an elegant way to solve several of the open questions in TeV-scale particle physics, it is by no means a unique solution. I will give an overview on different explanations for the observed structure of particles and interactions, ranging from the old idea of a Higgless Standard Model (technicolor), recently revived in the context of extra dimensions, to topcolor and Little-Higgs models that provide a rich spectrum of new states in the TeV range.
