Abstract

Physics and Astronomy (miscellaneous)
The cross section for the process e+e-→γγ has been measured for c.m. energies 39.5+>61 GeV and Λ+> GeV (95% confidence level) have been determined. A search for two photon final states with missing energy provided lower limits on the masses of the photino and selectron.
