SUSY naturalness and implications for LHC, ILC, axion and wimp detection
I discuss electroweak naturalness in SUSY models and show that, if applied properly, then all three measures -- electroweak, Higgs mass and BG -- concur with one another. The essential feature of SUSY naturalness is the presence of light Higgsinos with mass the closer to m(h) the better. The expected spectra gives rise to a unique same-sign diboson signature for LHC but a definitive test will require ILC with sqrt(s)~500-600 GeV. In this case, the ILC would be a higgsino factory! The perfectly natural Little Hierarchy might be a reflection of mismatch between PQ breaking scale and hidden sector mass scale fa<<m(hidden). In this model, ultimate detection of both an axion and a higgsino-like wimp is expected. A ton-scale noble liquid detector should probe the entire model since the lightest Higgsino always contains a non-negligible gaugino component.
