Sensitivity of the ATLAS detector to extra dimensions in di-photon and di-lepton production processes

Sumario:The processes of photon and lepton pair production are studied in models where gravity can propagate in large extra dimensions. The signal and backgrounds are simulated for the ATLAS detector with use of the ATLFAST program. Discovery limits are obtained and possible theoretical uncertainties for the predictions are discussed. An optimal cutoff on lepton/photon pair invariant mass which maximizes the reach in the energy scale of the extra dimension is found.
