The Higgs-boson and top-quark candidates are identified in the all-hadronic decay mode, where H -- bb ?? and t -- bW -- bqq??0 are reconstructed as large-radius jets. The candidate Higgs boson, top quark, and associated B hadrons are identified using tagging algorithms. No significant excess is observed above the background, so limits are set on the production cross section of a singlet T quark at 95{\%} confidence level, depending on the mass mT and coupling ??T of the vectorlike T quark to Standard Model particles. In the considered mass range between 1.0 and 2.3 TeV, the upper limit on the allowed coupling values increases with mT from a minimum value of 0.35 for 1.07 < mT < 1.4 TeV to 1.6 for mT 1/4 2.3 TeV.", optnote="WOS:000810236400005", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5271), last updated on Mon, 04 Jul 2022 07:51:12 +0000", issn="2470-0010", doi="10.1103/PhysRevD.105.092012", opturl="https://arxiv.org/abs/2201.07045", opturl="https://doi.org/10.1103/PhysRevD.105.092012", language="English" }
