Resumen:
This article presents a search for high mass e e or mu
mu resonances in pp collisions at sqrt{s} = 7 TeV at the LHC. The data
were recorded by the ATLAS experiment during 2010 and correspond to a
total integrated luminosity of ~40/pb. No statistically significant
excess above the Standard Model expectation is observed in the search
region of dilepton invariant mass above 110 GeV. Upper limits at the 95%
confidence level are set on the cross section times branching ratio of
Z' resonances decaying to dielectrons and dimuons as a function of the
resonance mass. A lower mass limit of 1.048 TeV on the Sequential
Standard Model Z' boson is derived, as well as mass limits on Z* and
E(6)-motivated Z' models.
