(a) The invariant mass distributions () for signal and background () of the photon pair after applying the cuts defined in (18) at the 14 TeV LHC. (b) The angular distributions () for signal and background after applying the cuts defined in (19) at the 14 TeV LHC. For both plots, we take 1.5, 2.0, and 2.5 TeV and for signal and for both signal and background. The background in (b) is shown after multiplying by a factor of 50.
