Abstract: | <jats:title>A<jats:sc>bstract</jats:sc> </jats:title> <jats:p>The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to an electron-positron pair or a muon-antimuon pair. The search is sensitive to heavy neutral <jats:italic>Z′</jats:italic> gauge bosons, Randall-Sundrum gravitons, <jats:italic>Z</jats:italic> <jats:sup>*</jats:sup> bosons, techni-mesons, Kaluza-Klein <jats:italic>Z/γ</jats:italic> bosons, and bosons predicted by Torsion models. Results are presented based on an analysis of <jats:italic>pp</jats:italic> collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 4.9 fb<jats:sup>−1</jats:sup> in the <jats:italic>e</jats:italic> <jats:sup>+</jats:sup> <jats:italic>e</jats:italic> <jats:sup>−</jats:sup> channel and 5.0 fb<jats:sup>−1</jats:sup> in the <jats:italic>μ</jats:italic> <jats:sup>+</jats:sup> <jats:italic>μ</jats:italic> <jats:sup>−</jats:sup>channel. A <jats:italic>Z</jats:italic> <jats:sup>′</jats:sup> boson with Standard Model-like couplings is excluded at 95 % confidence level for masses below 2.22 TeV. A Randall-Sundrum graviton with coupling <jats:inline-formula> <jats:tex-math>$ {k \left/ {{{{\overline{M}}_{\mathrm{Pl}}}}} \right.}=0.1 $</jats:tex-math> </jats:inline-formula> is excluded at 95 % confidence level for masses below 2.16 TeV. Limits on the other models are also presented, including Technicolor and Minimal <jats:italic>Z′</jats:italic> Models.</jats:p> |
