High-scale SUSY from an R-invariant New Inflation in the Landscape
  We provide an anthropic reason that the supersymmetry breaking scale is much
higher than the electroweak scale as indicated by the null result of collider
experiments and observed 125 GeV Higgs boson. We focus on a new inflation model
as a typical low-scale inflation model that may be expected in the string
landscape. In this model, the R-symmetry is broken at the minimum of the
inflaton potential and its breaking scale is related to the reheating
temperature. Once we admit that the anthropic principle requires thermal
leptogenesis, we obtain a lower bound on gravitino mass, which is related to
R-symmetry breaking scale. This scenario and resulting gravitino mass predict
the consistent amplitude of density perturbations. We also find that string
axions and saxions are consistently implemented in this scenario.
