Search for Large Extra Dimensions at the LHC with Center-Edge Asymmetry

Abstract

We study the possibility of using the center-edge asymmetry to distinguish spin-2 Kaluza-Klein graviton exchange within the ADD scenario from other new physics effects described by spin-1 exchange in lepton-pair production at the LHC. We find that the LHC detectors will be capable of discovering and identifying graviton spin-2 exchange effects in the ADD scenario with Ms ranging from 4.6 TeV to 9.4 TeV depending on luminosity and number of extra dimensions.
