Search for diboson resonances with boson-tagged jets in pp collisions at √s=13 TeV with the ATLAS detector

Narrow resonances decaying into WW, WZ or ZZ boson pairs are searched for in 36.7 fb −1 of proton–proton collision data at a centre-of-mass energy of s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The diboson system is reconstructed using pairs of large-radi...
