Search for a Z′ resonance in dilepton decays with the ATLAS — •Igor Potrap, Oliver Kortner, and Hubert Kroha — Max-Planck-Institut fuer Physik, Munich, Germany
The ATLAS physics potential for the search of a Z′ dilepton resonance has been studied under the assumption that heavy Z′ bosons have the same couplings as the Standard Model Z boson. The exclusion limit on the Z′ mass reached by the Tevatron is m<1 TeV. The ATLAS experiment allow for significantly improved mass reach already for the initial LHC data taking at 7 TeV center-of-mass energy. An integrated luminosity of around 50 pb−1 is enough to reach the Tevatron exclusion limits. A Z′ dilepton resonance with a mass of about 1 TeV can be observed with a total luminosity of 100 pb−1 and a luminosity of about 1 fb−1 is required to expand the discovery range up to 1.5 TeV. The results from the first proton-proton collisions in ATLAS in 2010 are discussed.
