Searches for electroweak production of higgsino with ATLAS

Fine-tuning arguments suggest the mass of the supersymmetric partner of the Higgs boson, the Higgsino, is not too far from the weak scale. In most beyond standard model scenarios the Higgsinos are almost mass degenerate, and the search for Higgsinos represents an experimental challenge due to the ne...

Sumario:Fine-tuning arguments suggest the mass of the supersymmetric partner of the Higgs boson, the Higgsino, is not too far from the weak scale. In most beyond standard model scenarios the Higgsinos are almost mass degenerate, and the search for Higgsinos represents an experimental challenge due to the near mass-degeneracy resulting in soft decay products, and the low production cross section. This proceeding presents recent ATLAS results of analyses explicitly targeting the Higgsino with a variety of experimental techniques.
