dc.description.abstractA search for the pair production of heavy vectorlike partners T and B of the top and bottom quarks has been performed by the CMS experiment at the CERN LHC using proton–proton collisions at ? s = 13 TeV. The data sample was collected in 2016 and corresponds to an integrated luminosity of 35.9 fb?1. Final states studied for TT production include those where one of the T quarks decays via T ? tZ and the other via T ? bW, tZ, or tH, where H is a Higgs boson. For the BB case, final states include those where one of the B quarks decays via B ? bZ and the other B ? tW, bZ, or bH. Events with two oppositely charged electrons or muons, consistent with coming from the decay of a Z boson, and jets are investigated. The number of observed events is consistent with standard model background estimations. Lower limits at 95% confidence level are placed on the masses of the T and B quarks for a range of ranching fractions. Assuming 100% branching fractions for T ? tZ, and B ? bZ, T and B quark mass values below 1280 and 1130 GeV, respectively, are excluded.en_US
