Search for dilepton resonances in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

ATLAS Collaboration

Understand

This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states.

The data were recorded by the ATLAS experiment in pp collisions at sqrt(s) = 7 TeV at the LHC and correspond to a total integrated luminosity of 1.08/fb (1.21/fb) in the ee (mumu) channel.
No statistically significant excess above the Standard Model expectation is observed and upper limits are set at the 95% C.L.
on the cross section times branching ratio of Z' resonances and Randall-Sundrum gravitons decaying into dileptons as a function of the resonance mass.
