Combination of CDF and D0 Limits on a Gauge Mediated SUSY Model Using   Diphoton and Missing Transverse Energy Channel
  We combine the results of the CDF and D0 searches for chargino and neutralino production in Gauge-Mediated SUSY using the two-photon and missing Et channel. The data are p-pbar collisions produced at the Tevatron with sqrt(s)=1.96 TeV, with 202 pb^-1 collected at CDF and 263 pb^-1 collected at D0. The combined limit excludes a chargino mass less than 209 GeV/c^2. This result significantly extends the individual experimental limits.
