Slepton Oscillation at e-gamma Colliders

Abstract

We study the possible signature for lepton-flavor violation processes in the scalar-lepton sector of the minimal supersymmetric model at future electron-photon colliders. We find that an $\text{egm}$ collider can provide a good opportunity to probe the mass differences and flavor mixing angles between the sleptons of the first generation and the other two generations for the right-handed as well as the left-handed sector. The sensitivity reach for lepton-flavor violation is comparable to that obtained at an $e^{+}{e}^{-}$ and $e^{-}{e}^{-}$ collider, and is significantly better than the current bound from low-energy rare processes such as $\mu \to e\gamma$.
