Abstract:

The discovery of an apparently elementary Standard-Model-like Higgs boson
strengthens the deep mystery surrounding physics at the TeV energy scale.  Almost all
theories of the origin of the Higgs and the associated scale of electroweak symmetry
breaking either have dynamically unnatural parameters, or severely lack explanatory
power for most features of the Standard Model.  I explain these issues and show
how a radically different way of implementing a supersymmetric version of the
Standard Model, ``Maximally Natural Supersymmetry,” can explain, without fine-tuning,
the weak scale and the observed Higgs boson.  This class of theories intrinsically involves
extra dimensions, and has much different physics than the usual Minimal Supersymmetric
Standard Model and its extensions.
