Search for a Heavy Particle Decaying into an Electron and a Muon with the ATLAS Detector in √s=7 TeV pp collisions at the LHC
This Letter presents the first search for a heavy particle decaying into an e[superscript ±]μ[superscript ∓] final state in √s=7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of 35 pb[superscript -1]. No exces...

| description | This Letter presents the first search for a heavy particle decaying into an e[superscript ±]μ[superscript ∓] final state in √s=7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of 35 pb[superscript -1]. No excess above the standard model background expectation is observed. Exclusions at 95% confidence level are placed on two representative models. In an R-parity violating supersymmetric model, tau sneutrinos with a mass below 0.75 TeV are excluded, assuming all R-parity violating couplings are zero except λ[subscript 311][superscript ′]=0.11 and λ[subscript 312]=0.07. In a lepton flavor violating model, a Z[superscript ′]-like vector boson with masses of 0.70–1.00 TeV and corresponding cross sections times branching ratios of 0.175–0.183 pb is excluded. These results extend to higher mass R-parity violating sneutrinos and lepton flavor violating Z’s than previous constraints from the Tevatron. |
