摘要

Mass limits are presented for various supersymmetric particles: scalar partners of electrons, muons, taus and quarks; photinos, winos and zinos. They were obtained from the analysis of an exposure of 48.6 pb−1 of the CELLO detector at the PETRAe+e− storage ring up to a center of mass energy of 46.8 GeV. Special attention has been given to the case where the photino is assumed to be the lightest supersymmetric particle, but other possibilities have also been considered.
