Search for Large Extra Dimensions via Single Photon plus Missing Energy Final States at sqrt(s) = 1.96 TeV

Abstract

We report on a search for large extra dimensions in a data sample of approximately 1 fb^{-1} of ppbar collisions at sqrt(s) = 1.96 TeV. We investigate Kaluza-Klein graviton production with a photon and missing transverse energy in the final state. At the 95% C.L. we set limits on the fundamental mass scale M_{D} from 884 GeV to 778 GeV for two to eight extra dimensions.
