This talk will present the most recent results of high mass resonance searches in the diphoton final state. The talk will include results from Randall Sundrum graviton searches (Exotica). Those searches are based on the full 2012 data collected from pp collisions at a center of mass energy of 8 TeV, corresponding to an integrated luminsosity of 19.6 \fb. Such searches are essential to address the hierarchy mass problem and would help understand the unification of the four fundamental forces. The theoretical motivation will be introduced, the selection and its efficiency presented and the background determination techniques explained. Finally, the data/background comparison results will be shown as well as the limits on the mass of the first excitation of the RS graviton.
