 Description Naturalness, or fine-tuning, in one of the primary motivations for weak-scale supersymmetry (SUSY). 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.
