Search for dark matter and large extra dimensions in pp collisions yielding a photon and missing transverse energy

Abstract: Results are presented from a search for new physics in the final state containing a photon (?) and missing transverse energy (E?T). The data correspond to an integrated luminosity of 5.0??fb?1 collected in pp collisions at ?s=7??TeV by the CMS experiment. The observed event yield agrees with standard-model expectations for the ?+E?T events. Using models for the production of dark-matter particles (?), we set 90% confidence level (C.L.) upper limits of 13.6?15.4 fb on ? production in the ?+E?T state. These provide the most sensitive upper limits for spin-dependent ?-nucleon scattering for ? masses (M?) between 1 and 100 GeV. For spin-independent contributions, the present limits are extended to M?<3.5??GeV. For models with 3?6 large extra dimensions, our data exclude extra-dimensional Planck scales between 1.64 and 1.73 TeV at 95% C.L.
