Jets in the final state are classified using a deep neural network as arising from hadronically decaying W/Z bosons, Higgs bosons, top quarks, or background. The analysis uses data from the ATLAS experiment corresponding to 36.1 fb(-1) of proton-proton collisions with a center-of-mass energy of root s = 13 TeV delivered by the Large Hadron Collider in 2015 and 2016. No significant deviation from the Standard Model expectation is observed. Results are interpreted assuming the vectorlike quarks decay into a Standard Model boson and a third-generation-quark, T -> Wb, Ht, Zt or B -> Wt, Hb, Zb, for a variety of branching ratios. At 95{\%} confidence level, the observed (expected) lower limit on the vectorlike B-quark mass for a weak-isospin doublet (B, Y) is 950 (890) GeV, and the lower limits on the masses for the pure decays B -> Hb and T -> Ht, where these results are strongest, arc 1010 (970) GeV and 1010 (1010) GeV, respectively.", optnote="WOS:000449782800001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3799), last updated on Mon, 26 Nov 2018 18:05:37 +0000", issn="2470-0010", doi="10.1103/PhysRevD.98.092005", opturl="http://arxiv.org/abs/1808.01771", opturl="https://doi.org/10.1103/PhysRevD.98.092005", archivePrefix="arXiv", eprint="1808.01771", language="English" }
