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

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 √s=7TeV at the Large Hadron Collider and correspond to a total integrated luminosity of 1.08 (1.21)fb - 1 in the e + e - (μ + μ - )...
