Gravitational Wave Probe of High Supersymmetry Breaking Scale
  A supersymmetric standard model with heavier scalar particles is very
interesting from various viewpoints, especially Higgs properties. If the scalar
mass scale is O(10-10^4) TeV, the standard model-like Higgs with mass around
125 GeV, which is implied by the recent LHC experiments, is predicted. However
this scenario is difficult to be directly tested with collider experiments. In
this paper, we propose a test of this scenario by using observations of
primordial gravitational waves (GWs). The future GW experiments such as DECIGO
and BBO can probe the scalar mass around O(10^3-10^4) TeV, which is preferred
from the Higgs mass about 125 GeV, if the primordial GWs have large amplitude.
