Gravitational Wave Probe of High Supersymmetry Breaking Scale

Understand

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).
