| Abstract | A study for a noncommutative (NC) black hole was performed using data recorded by the ATLAS detector using proton-proton collisions at a centre-ofmass energy of 7 TeV with an integrated luminosity of 502± 9 pb−1. A missing transverse energy trigger was used in this search. The efficiency of the trigger versus reconstructed missing transverse energy was determined. A missing transverse energy requirement was imposed in the analysis so that the trigger was at its maximum efficiency. A black hole production process having a cross-section of 4.67 pb was simulated with eight total dimensions, a higher dimensional Planck scale of 0.94 TeV and a black hole remnant mass of 3.6 TeV. The main goal of this thesis is to search study NC black holes in the ATLAS data. To achieve this, simulated Standard Model backgrounds events were used: QCD, tt̄, W+ jets and Z+jets processes. The significance of a possible black hole discovery using the ATLAS detector at the LHC was estimated after optimizing the signal yield and reducing the Standard Model simulated background contribution through the application of some derived selection criteria. |
