This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp
collisions and decaying to all-hadronic final states. The data used in
the analysis were recorded by the ATLAS detector at the CERN Large
Hadron Collider at a centre-of-mass energy of and correspond to an integrated luminosity of . The measurement is performed by reconstructing the boosted W or Z bosons in single jets. The reconstructed jet mass is used to identify the W and Z
bosons, and a jet substructure method based on energy cluster
information in the jet centre-of-mass frame is used to suppress the
large multi-jet background. The cross-section for events with a
hadronically decaying W or Z boson, with transverse momentum and pseudorapidity , is measured to be
pb and is compared to next-to-leading-order calculations. The selected
events are further used to study jet grooming techniques.
