Abstract

The sensitivity of the CMS experiment to the resonant production of massive Kaluza-Klein excitations of gravitons, expected in the framework of the Randall-Sundrum model, is studied. Full simulation and reconstruction are used to investigate this production followed by graviton decay to an pair. For a Randall-Sundrum model with coupling parameter c = 0.01, the graviton excitations have weak couplings to Standard Model particles. For an integrated luminosity of 100 fb^-1, resonances can be discovered at the level for masses up to 1.8 TeV/c ². Heavier resonances are accessible for larger values of the c parameter, with a mass reach of 3.8 TeV/c ² for c = 0.1.
