Highly boosted hadronically decaying particles have been widely used as a unique signature to search for NP at the LHC. In this talk, we present 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 by ATLAS experiment. The measurement is performed by reconstructing 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 center-of-mass frame is used to suppress the large multi-jet background. In this talk, we will also discuss potential applications of the jet substructure in the jet rest frame in searches for NP at the LHC.
