Abstract
A search for new physics has been carried out in the channel , as expected in various supersymmetric models. We require two photons with transverse energy and pseudorapidity . The distribution of missing transverse energy ( ) is consistent with background and no events have . We set limits on production cross sections for selectron, sneutrino, and neutralino pairs, decaying into photons, which range from about 400 fb to 1 pb depending on the sparticle masses. A general limit of 185 fb (95% C.L.) is set on , where , , and .
