ATLAS experiment searches for natural supersymmetry using novel techniques
(PHYSorg.com Physics)

In new results presented at CERN, the ATLAS Experiment`s search for supersymmetry (SUSY) reached new levels of sensitivity. The results examine a popular SUSY extension studied at the Large Hadron Collider (LHC): the `Minimal Supersymmetric Standard Model` (MSSM), which includes the minimum required number of new particles and interactions to make predictions at the LHC energies. However, even this minimal model introduces a large amount of new parameters (masses and other properties of the new particles), whose values are not predicted by the theory (free parameters).
