Search for large extra dimensions in dimuon and dielectron events in pp
collisions at sqrt(s) = 7 TeV    [PDF]

CMS Collaboration

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 sqrt(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 inverse femtobarns. The observed dimuon and
dielectron mass spectra are found to be consistent with standard-model
expectations. Depending on the number of extra dimensions, the limits at 95%
confidence level are in the range 2.5 TeV < Ms < 3.8 TeV, where Ms
characterizes the scale for the onset of quantum gravity.
