description The CMS detector discovery potential to the resonant production of massive Kaluza - Klein excitations expected in Randall-Sundrum model is studied. Full simulation and reconstruction are used to study diphoton decay of Randall-Sundrum gravitons. For an integrated luminosity of 30 fb^-1 diphoton decay of Randall-Sundrum graviton can be discovered at 5 sigma level for masses up to 1.61~tevsucqua in case of weak coupling between graviton excitations and Standard model particles (c=0.01). Heavier resonances can be detected for larger coupling constant (c=0.1), with mass reach of 3.95~tevsucqua.
