SUSY Naturalness and Light Higgsinos
In this talk I will examine the implications of naturalness, or fine-tuning, in supersymmetry (SUSY) in light of recent LHC results. Although fine-tuning is intrinsically model dependent, we show that it is possible to perform a phenomenological analysis in a model independent way using the electroweak fine-tuning parameter. We argue that the presence of light higgsinos, rather than often-cited light stops, is the most basic consequence of SUSY naturalness. Current search strategies at LHC are inefficient for such scenario and we introduce novel diboson signatures. Finally, we will discuss capabilities of LHC14 and ILC to completely probe SUSY naturalness.
