Title: | 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=13TeV with the ATLAS detector | Authors: | Santos, S. P. Amor dos Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2019 | Publisher: | Elsevier | Serial title, monograph or event: | Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics | Volume: | 788 | Abstract: | 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 | URI: | https://hdl.handle.net/10316/107220 | DOI: | 10.1016/j.physletb.2018.09.062 | Rights: | openAccess |
