| Abstract: A search for electroweak production of a single vector-like quark T in association with a bottom quark (b) and decaying fully hadronically is presented. This search uses proton-proton collision data at $ \sqrt{s} = $ 13 TeV collected by the CMS experiment at the CERN LHC during 2016-2018, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The T can have charge 2/3 and can decay to a top quark (t) and a Higgs or Z boson. Event kinematics and the presence of jets containing b hadrons are used to reconstruct the hadronic decays of the t and Higgs or Z boson. No discrepancy from the standard model prediction is observed in the data. For T masses from 600 to 1200 GeV, the 95% confidence level upper limits on the production cross section of a T produced in association with a b and decaying via a t and a Higgs or Z boson range from 1260 to 68 fb. | ||
