Search for Physics beyond the Standard Model with the ATLAS detector in final states with high-pT leptons — •Giovanni Siragusa for the ATLAS collaboration — Julius-Maximilians-Universität, Würzburg, Germany
The center-of-mass energies available at the LHC provide an excellent opportunity to test the Standard Model and search for New Physics. Exotic searches play a key role by testing a large variety of predictions and exploring a large number of different final states, which cover a huge part of the available phase space. Until now no relevant discrepancy has been observed and the various searches have been interpreted in terms of exclusion limits.
Signals containing high-pT leptons in the final state are predicted in many extensions of the Standard Model, while such signatures are more rare in background processes. As a consequence, when high-pT leptons are selected, the signal to background ratios are enhanced and the experimental sensitivity is increased. In this talk I will present a review of Exotics searches performed by the ATLAS experiment using 20 fb−1 of data collected at √s=8 TeV in a variety of final states containing high-pT leptons.
