Introduction to Supersymmetry (1/4)

In these lectures, I will introduce supersymmetry as an extension to spacetime symmetries both formally and physically.  I will present motivations for why we think supersymmetry may exist in the real world, and may manifest itself at the LHC.  I will describe the current set of models of softly broken supersymmetry at the electroweak scale and the parts that make them exciting and the parts that make people sick.  I will then cover the phenomenology of the various models - the spectra and some of the best studied collider signals.  Finally, I will describe the phenomenology of the full supersymmetric parameter space in general terms and discuss this collider signals not covered by the classic models.
