Supersymmetry

In modern physics symmetries play a central role - like in arts - because the principles of nature are manifested by them. The most general symmetry of the laws of nature is called Supersymmetry (SUSY). It is a symmetry between matter particles (fermions) and force particles (bosons) and it offers the possibility of imbedding our today´s knowledge about the basic structure of matter (the so-called Standard Model) into a larger, more general theory.

 

In a supersymmetric theory fermions and bosons appear pairwise. If nature is supersymmetric, there is a supersymmetric "doppelgänger" state to every presently known elementary particle. The search for SUSY is one of the prime science goals of LHC at CERN and motivates the construction of future Linear electron-positron colliders.

Presently, our group investigates the following cases:

  • SUSY phenomenology at LHC and at a future Linear e+e- collider
  • SUSY-Higgs decays
  • Radiative corrections to processes with SUSY particles
  • Quark flavour violation (QFV)
  • Gravitino physics
  • Two Higgs Doublett models
  • CP violation in SUSY

Our group was supported from 2014 - 2016 by the grant P 26338-N27 from the Austrian Science Fund (FWF).
