Title: Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at √s = 7 TeV with the ATLAS detector

Abstract

This article 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 $$\sqrt{s}=7\;{\rm Te}{\rm V}$$ and correspond to an integrated luminosity of $$4.6\;{\rm f}{{{\rm b}}^{-1}}$$. 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 $${{p}_{{\rm T}}}\gt 320\;{\rm Ge}{\rm V}$$ and pseudorapidity $$|\eta |\lt 1.9$$, is measured to be $${{\sigma }_{W+Z}}=8.5\pm 1.7$$ pb and is compared to next-to-leading-order calculations. The selected events are further used to study jet grooming techniques.
