Abstract:
We explore the potential of electron-photon colliders to measure fundamental supersymmetry parameters via the processes (selectron-neutralino) and (sneutrino-chargino). Given the and masses from and hadron collider studies, cross section ratios for opposite photon helicities determine the , and masses, independent of the sparticle branching fractions. The difference measures in a model-independent way. The and masses test the universality of soft supersymmetry breaking scalar masses. The cross section normalizations provide information about the gaugino mixing parameters.- photon electron: exclusive reaction
