PROSPECTS FOR IDENTIFYING NEW PHYSICS SCENARIOS AT CERN LHC

Abstract

The signatures of the spin-2 graviton excitations predicted by the Randall – Sundrum model with one warped extra dimension, in dilepton and diphoton production at LHC were studied. By using the center – edge asymmetry, we evaluate the ranges of mass and coupling constant where such gravitons can be discriminated against competitor spin-1 and spin-0 objects that could potentially manifest themselves in these processes. Depending on the value of coupling constants, the numerical results allow one to obtain graviton identification mass ranges of the order of 2.4 TeV and 3.2 TeV for LHC nominal energy of 14 TeV and time-integrated luminosity of 100 fb–1.
