Search for high-mass diboson resonances with boson-tagged jets in proton-proton collisions at √s = 8TeV with the ATLAS detector

Abstract: A search is performed for narrow resonances decaying into WW, WZ, or ZZ boson pairs using 20.3 fb −1 of proton-proton collision data at a centre-of-mass energy of s=8$$ \\sqrt{s}=8 $$ TeV recorded with the ATLAS detector at the Large Hadron Collider. Diboson resonances with masses in the r...
