The search is interpreted in terms of both a left-handed and a right-handed chiral boson within the mass range 1–5 TeV. Identification of the hadronically decaying top quark is performed using jet substructure tagging techniques based on a shower deconstruction algorithm. No significant deviation from the Standard Model prediction is observed and the results are expressed as upper limits on the <math><msup is="true"><mrow is="true"><mi is="true">W</mi></mrow><mrow is="true"><mo is="true">′</mo></mrow></msup><mo stretchy="false" is="true">→</mo><mi is="true">t</mi><mover accent="true" is="true"><mrow is="true"><mi is="true">b</mi></mrow><mrow is="true"><mo stretchy="false" is="true">¯</mo></mrow></mover></math> production cross-section times branching ratio as a function of the W'-boson mass. These limits exclude W' bosons with right-handed couplings with masses below 3.0 TeV and W' bosons with left-handed couplings with masses below 2.9 TeV, at the 95% confidence level.
