Breaking of supersymmetry at intermediate energy

Abstract

We consider the proposal that supersymmetry is broken at a scale $\mu$ midway between the Planck scale $M$ and the usual weak scale. We show how a phenomenological explicitly softly broken supersymmetric theory can emerge below scale $\mu$. The characteristic scale for the explicit supersymmetry breaking is of order $\frac{\alpha {\mu }^2}{M}$. Identifying this with the weak scale ∼250 GeV gives $\mu \sim {10}^{12}$ GeV.
