Gravitational Wave Probe of High Supersymmetry Breaking Scale    [PDF]

Ryo Saito, Satoshi Shirai
A supersymmetric standard model with heavier scalar particles is very interesting from various viewpoints, especially Higgs properties. If the scalar mass scale is O(10-10^3) 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 very difficult to be directly tested with collider experiments. In this paper, we propose a test of this scenario by using the gravitational wave (GW) experiments as DECIGO and BBO. The future GW experiments can probe the scalar mass around O(10^2-10^3) TeV, which is preferred from the Higgs mass about 125 GeV.
