This search uses proton-proton collision data at root 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 quark is assumed to have charge 2/3 and decay to a top (t) quark and a Higgs (H) or Z boson. Hadronic decays of the t quark and the H or Z boson are reconstructed from the kinematic properties of jets, including those containing b hadrons. No deviation from the standard model prediction is observed in the reconstructed tH and tZ invariant mass distributions. The 95% confidence level upper limits on the product of the production cross section and branching fraction of a T quark produced in association with a b quark and decaying via tH or tZ range from 1260 to 68 fb for T quark masses of 600-1200 GeV.eninfo:eu-repo/semantics/openAccessSearch for Production of a Single Vectorlike Quark Decaying To Th or Tz in the All-Hadronic Final State in Pp Collisions at √s=13 TevFormula PresentedArticle10.1103/PhysRevD.110.0720122-s2.0-85210771927
