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.
