Gauge-mediated supersymmetry breaking signals in an electron-photon collider

Abstract

We show the usefulness of an ${e}^{\ensuremath{-}}\ensuremath{\gamma}$ collider with backscattered laser photons in unveiling the signatures of gauge-mediated supersymmetry breaking models, with a right selectron as the next LSP. We also show how the signal can be distinguished from the standard model background as well as from signals of minimal supersymmetry.
