Search for light resonances decaying to boosted quark pairs and produced in association with a photon or a jet in proton–proton collisions at √s= 13 TeV with the ATLAS detector Aaboud, M. Aguilar Saavedra, Juan Antonio Atlas Collaboration We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently. The crucial computing support from all WLCG partners is ac-knowledged gratefully, in particular from CERN, the ATLAS Tier-1facilities at TRIUMF (Canada), NDGF (Denmark, Norway, Swe-den), CC-IN2P3 (France), KIT/GridKA (Germany), INFN-CNAF (Italy), NL-T1 (Netherlands), PIC (Spain), ASGC (Taiwan), RAL (UK) and BNL (USA), the Tier-2 facilities worldwide and large non-WLCG resource providers. Major contributors of computing resources are listed in Ref.[61]. This Letter presents a search for new light resonances decaying to pairs of quarks and produced in association with a high-pTphoton or jet. The dataset consists of proton–proton collisions with an integrated luminosity of 36.1 fb−1at a centre-of-mass energy of √s=13TeV 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. 2019-11-26T11:40:07Z 2019-11-26T11:40:07Z 2018-11-02 info:eu-repo/semantics/article The ATLAS Collaboration.
