Distinguishing Majorana and Dirac Gluinos and Neutralinos

Understand

While gluinos and neutralinos are Majorana fermions in the MSSM, they can be Dirac fermion fields in extended supersymmetry models.

• The difference between the two cases manifests itself in production and decay processes at colliders.
• In this contribution, results are presented for how the Majorana or Dirac nature of gluinos and neutralinos can be extracted from di-lepton signals at the LHC.
