2009 CMS Discovery Reach for Randall Sundrum Gravitons in the Diphoton Channel Randall-Sundrum (RS) models propose to resolve the hierarchy problem of the SM with a warped extra dimension of space. Gravity scale = MPl exp(-krc) ~TeV; for krc ~11-12, no hierarchy prob Gravitons in this model appear as high mass resonances, mn = xn k exp(-krc), J1(xn)=0 The masses and widths determined by the parameters M1 and k We probe the discovery of RS gravitons in the diphoton channel Studies published in PTDR: 10 fb -1 : M G > 3.5 TeV for c=0.1; M G > 1.3 TeV for c=0.01 Updated results with latest software
