Exceptional Supersymmetry at the LHC
Peter Athron (TU Dresden)

Supersymmetry is one of the best motivated possibilities for new physics discovery at the Large Hadron Collider. In addition to the commonly studied Minimal Supersymmetric Standard Model, Supersymmetry (MSSM) may also be realised in non-minimal SUSY models. I will motivate and describe non-minimal realisations of supersymmetry, with a particular focus on the Exceptional Supersymmetric Standard Model (E6SSM), inspired by Grand Unified Theories based on the E6 exceptional Lie group. The E6SSM matter content fills three generations of E6 multiplets, thus predicting exotic new matter and, inspired by E6 breaking, has an extra U(1)_N gauge group broken at low energies (along with the EW symmetry), which solves the mu-problem of the MSSM. I will discuss the phenomenology including detailed mass spectra, with particular reference to the LHC, as well as discussing other recent progress.
