abstract = {A search for a massive $W'$ gauge boson is performed with
the ATLAS detector at the LHC in pp collisions at a
centre-of-mass energy of $\sqrt{s}$ = 8 TeV, corresponding
to 20.3 fb$^{-1}$ of integrated luminosity. This analysis is
done in the $W' \rightarrow tb \rightarrow qqbb$ mode for
$W'$ masses above 1.5 TeV, where the $W'$ decay products are
highly boosted. Novel jet substructure techniques are used
to identify jets from high-momentum top quarks to ensure
high sensitivity, independent of $W'$ mass, up to 3 TeV;
b-tagging is also used to identify jets originating from
b-quarks. The data are consistent with Standard Model
background-only expectations, and upper limits at 95\%
confidence level are set on the $W' \rightarrow tb$ cross
section times branching ratio ranging from 0.16 pb to 0.33
pb for left-handed $W'$ bosons, and ranging from 0.10 pb to
0.21 pb for $W'$ bosons with purely right-handed couplings.
Upper limits at 95\% confidence level are set on the
$W'$-boson coupling to tb as a function of the $W'$ mass
using an effective field theory approach, which is
independent of details of particular models predicting a
$W'$ boson.},
