000003221 520__ $$aWe carried out the feasibility study of the dark-photon searches for events where only a single photon is detected, using signal and background Monte-Carlo simulation.  The backgrounds are dominated by the radiative Bhabha and three-photon production processes. Signal sensitivities are studied by changing the requirements for the responses in the calorimeter and KL-muon detector.
