Abstract
This Letter reports a search for a heavy particle that decays to WW using events produced in pp collisions at √s=7TeV. The data were recorded in 2011 by the ATLAS detector and correspond to an integrated luminosity of 4.7 fb⁻¹. WW→ℓνℓ′ν′WW→ℓνℓ′ν′ (ℓ,ℓ′=eℓ,ℓ′=e or μ) final states are considered and the distribution of the transverse mass of the WW candidates is found to be consistent with Standard Model expectations. Upper limits on the production cross section times branching ratio into W boson pairs are set for Randall–Sundrum and bulk Randall–Sundrum gravitons, which result in observed 95% CL lower limits on the masses of the two particles of 1.23 TeV and 0.84 TeV, respectively.
