Abstract
A search is presented for narrow diboson resonances decaying to $$WW$$WW or $$WZ$$WZ in the final state where one W boson decays leptonically (to an electron or a muon plus a neutrino) and the other W/Z boson decays hadronically. The analysis is performed using an integrated luminosity of 20.3 fb-1 of pp collisions at √s=8 TeV collected by the ATLAS detector at the large hadron collider. No evidence for resonant diboson production is observed, and resonance masses below 700 and 1490 GeV are excluded at 95 \% confidence level for the spin-2 Randall--Sundrum bulk graviton G* with coupling constant of 1.0 and the extended gauge model W′ boson respectively. \copyright 2015, CERN for the benefit of the ATLAS collaboration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
