Dark matter, extra dimensions, and Z decays at CMS
Abstract: CMS has collected 5-fb of proton-proton collision data during the 2011 LHC running at 7 TeV. Presented is the analysis of collisions in which a single photon recoils from invisible particles. The results are consistent with the predicted cross section of Z bosons decaying to neutrino pairs. Subsequently, competitive limits are placed on ADD large extra dimensions, and a model of dark matter.
