Spin Determination of Randall-Sundrum Graviton Excitations Decaying Into Two Photons at the LHC with ATLAS .
A. A. Pankov, I. A. Serenkova, and A. V. Tsytrinov

The ability of the ATLAS experiment at the Large Hadron Collider to detect massive Kaluza-Klein excitations of gravitons and determine their spin is discussed. The search reach is estimated for the channel with the graviton, produced in proton-proton collision, decaying into a pair of photons. A method for determining the graviton’s spin-2 nature by analyzing angular distributions of it’s photon decay products via the integrated center-edge asymmetry is presented.
Key words: Randall-Sundrum graviton, experiment ATLAS at LHC
