A bstractIn searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high transverse momenta from jets initiated by single partons. Algorithms are defined to identify such W jets for different signals of interest, using techniques that are also applicable to other decays of bosons to hadrons that result in a single jet, such as those from highly boosted Z and Higgs bosons. The efficiency for tagging W jets is measured in data collected with the CMS detector at a center-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. The performance of W tagging in data is compared with predictions from several Monte Carlo simulators.

- A new method to distinguish hadronically decaying boosted Z bosons from W bosons using the ATLAS detector (2015, unknown): “Both ATLAS [2] and CMS [3] have performed detailed comparisons of the various tagging variables and jet-grooming techniques with the overall conclusion that large QCD multijet suppression factors1 are possible while maintaining acceptable levels of boson tagging efficiency.”
- Looking Inside Jets (2019, methodology): “CMS [220, 221] takes a similar approach to W boson and top quark tagging as ATLAS.”
- Learning to Pivot with Adversarial Networks (2016, methodology): “The classification challenge used here is common in jet substructure studies (see e.g. (CMS Collaboration, 2014; ATLAS Collaboration, 2015, 2014)): we aim to distinguish normal jets produced copiously at the LHC ( Y = 0 ) and from W -jets ( Y = 1 ) potentially coming from an exotic process.”
