Search for large extra dimensions in dimuon and dielectron events in pp collisions at root s=7 TeV

Results are presented from a search for large, extra spatial dimensions in events with either two isolated muons or two isolated electrons. The data are from proton-proton interactions at root s = 7 TeV collected with the CMS detector at the LHC. The size of the data sample corresponds to an integrated luminosity of approximately 2 fb(-1). The observed dimuon and dielectron mass spectra are found to be consistent with standard-model expectations. Depending on the number of extra dimensions, the 95% confidence level limits from the combined mu mu and ee channels range from M-s GT 2.4 TeV to M-s GT 3.8 TeV, where M-s characterizes the scale for the onset of quantum gravity.
