Search and identification of extra spatial dimensions at LHC

Abstract

We present an analysis, based on the center-edge asymmetry, to distinguish effects of extra dimensions within the Arkani-Hamed-Dimopoulos-Dvali (ADD) and Randall-Sundrum (RS) scenarios from other new physics effects in lepton-pair production at the CERN Large Hadron Collider LHC. Spin-2 and spin-1 exchange can be distinguished up to an ADD cutoff scale, M_H, of about 5 TeV, at the 95% CL. In the RS scenario, spin-2 resonances can be identified in most of the favored parameter space.
