Electron to Muon Conversion in Electron-Nucleus Scattering as a Probe of Supersymmetry

Abstract

We suggest that $e\to \mu$ conversion in low-energy electron-nucleus scattering is a new and potentially observable indirect signal of supersymmetry and should be searched for in experiment. We estimate the rate for this process in a straightforward calculation taking into account the existing constraint from non-observation of the $\mu \to e\gamma$ decay and find the cross-section to be $\sigma <10^{-8}$fb.
