ABSTRACT
A search for a massive [Formula see text] gauge boson decaying to a top quark and a bottom quark is performed with the ATLAS detector in [Formula see text] collisions at the LHC. The dataset was taken at a centre-of-mass energy of [Formula see text] and corresponds to [Formula see text] of integrated luminosity. This analysis is done in the hadronic decay mode of the top quark, where novel jet substructure techniques are used to identify jets from high-momentum top quarks. This allows for a search for high-mass [Formula see text] bosons in the range 1.5-3.0 [Formula see text]. [Formula see text]-tagging is used to identify jets originating from [Formula see text]-quarks. The data are consistent with Standard Model background-only expectations, and upper limits at 95 % confidence level are set on the [Formula see text] cross section times branching ratio ranging from [Formula see text] to [Formula see text] for left-handed [Formula see text] bosons, and ranging from [Formula see text] to [Formula see text] for [Formula see text] bosons with purely right-handed couplings. Upper limits at 95 % confidence level are set on the [Formula see text]-boson coupling to [Formula see text] as a function of the [Formula see text] mass using an effective field theory approach, which is independent of details of particular models predicting a [Formula see text] boson.
