Randall-Sundrum model with a small curvature and dielectron production at the LHC

Abstract

In the framework Randall-Sundrum-like scenario with the small curvature kappa (RSSC model), p_t-distributions for the dielectron production at the LHC are calculated. For the summary statistics taken at 7 TeV (L = 5 fb-1) and 8 TeV (L = 20 fb-1), the exclusion limit on the 5-dimensional gravity scale M_5 is found to be 6.35 TeV at 95% C.L. For sqrt(s) = 13 TeV and integrated luminosity 30 fb-1, the LHC search limit is estimated to be 8.95 TeV. These limits on M_5 are independent of kappa, provided the relation kappa << M_5 is satisfied.
