The dataset consists of proton-proton collisions with an integrated luminosity of 36.1 fb⁻¹ at a centre-of-mass energy of √s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Resonance candidates are identified as massive large-radius jets with substructure consistent with a particle decaying into a quark pair. The mass spectrum of the candidates is examined for local excesses above background. No evidence of a new resonance is observed in the data, which are used to exclude the production of a lepto-phobic axial-vector Z′ boson.enCC BY 4.0 (Attribution)©2018 The Authorshttp://creativecommons.org/licenses/by/4.0/PartonsDark matter (Astronomy)AstronomyPhysicsTransverse momentumQuarksProton-proton interactionsAstrophysicsLarge Hadron Collider (France and Switzerland)Jets (Nuclear physics)PhotonsarticleAaboud, M., G.
