Description
The string landscape statistical draw to large scalar soft masses leads to a mixed quasi-
degeneracy/decoupling solution to the SUSY flavor and CP problems where first/second
generation matter scalars lie in the 20-40 TeV range. With increasing first/second gen-
eration scalars, SUSY models actually become more natural due to two-loop RG effects
which suppress the corresponding third generation soft masses. This can also lead to
substantial parameter space regions which are forbidden by the presence of charge and/or
color breaking (CCB) minima of the scalar potential. We outline the allowed SUSY pa-
rameter space for the gravity-mediated three extra-parameter-non-universal Higgs model
NUHM3. The natural regions with m h ∼ 125 GeV, ∆ EW ~ 30 and decoupled first/second
generation scalar are characterized by rather heavy gluinos and EW gauginos, but with
rather small μ and top-squarks not far beyond LHC Run 2 limits. This scenario also
explains why SUSY has so far eluded discovery at LHC in that the parameter space with
small scalar and gaugino masses is all excluded by the presence of CCB minima.
