To Split or Not to Split

Physics
is at a crossroad that leads either to Naturalness or the Multiverse. While the
confirmation of gauge coupling unification in the early 90s gave a tremendous
boost to naturalness and to low energy SUSY, the lack of evidence
for new physics beyond the standard model at the LHC points to a paucity of new
particles near the weak scale. This suggests that the weak scale is tuned and
that supersymmetry, if present at all, is realized at higher energies. This
points to Split SUSY, a framework motivated by the String Landscape.  Fine-tuning
 electroweak symmetry breaking and the renormalization group evolution of
the scalar masses constrains Split model building and I review the expectations
at the LHC for the different possible Split SUSY particle spectra.
