CSIC ORCID; CMS Collaboration | Fecha de publicación: | 2012 | Editor: | Elsevier | Citación: | Physics Letters B 711(1): 15-34 (2012) | Resumen: | 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 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 μμ and ee channels range from M s>2.4 TeV to M s>3.8 TeV, where M s characterizes the scale for the onset of quantum gravity. | Descripción: | Open access: This article is published Open Access at sciencedirect.com.
