Constraining the Minimal Dirac Gaugino Model
Most SUSY searches at the LHC are optimised for the MSSM, where gauginos are Majorana particles. By introducing Dirac gauginos, we obtain an enriched phenomenology, from which considerable differences in LHC signatures are expected. Concretely, in the Minimal Dirac Gaugino Model (MDGSSM) we have an electroweakino sector extended by two extra neutralino and one extra chargino eigenstates. Furthermore, a small mass splitting between the bino- like and between wino- like states can be naturally induced leading to the presence of Long Live Particles (LLPs). Here we discuss current limits on the gluinos and squarks and on the electroweakino sector of the MDGSSM, derived from reinterpretion LHC results and by considering constraints from dark matter searches. Finally, we discuss the presence of scenarios with LLPs whose predominant signature has not been covered in LHC searches.
