Constraining the Selectron Mass in the Process e^- + gamma --> neutralino_1 +selectron_{L/R}^- --> e^- + 2 neutralino_1

Abstract

With the process $e^{-}\gamma \to {\tilde{\chi }}_1^0{\tilde{e}}_{L/R}^{-}\to e^{-}{\tilde{\chi }}_1^0{\tilde{\chi }}_1^0$ it is possible to constrain selectron masses above the kinematical limit of the pair production process in $e^{+}{e}^{-}$ colliders. We investigate these mass ranges and discuss the possibility to test the renormalization group equations for the selectron masses.
