Abstract
A search is described for the production of a pair of bottom-type vectorlike quarks (Formula Presented VLQs) with mass greater than 1000 GeV. Each Formula Presented VLQ decays into a Formula Presented quark and a Higgs boson, a Formula Presented quark and a Formula Presented boson, or a Formula Presented quark and a Formula Presented boson. This analysis considers both fully hadronic final states and those containing a charged lepton pair from a Formula Presented boson decay. The products of the Formula Presented boson decay and of the hadronic Formula Presented or Formula Presented boson decays can be resolved as two distinct jets or merged into a single jet, so the final states are classified by the number of reconstructed jets. The analysis uses data corresponding to an integrated luminosity of Formula Presented collected in proton-proton collisions at Formula Presented with the CMS detector at the LHC from 2016 to 2018. No excess over the expected background is observed. Lower limits are set on the Formula Presented VLQ mass at the 95% confidence level. These depend on the Formula Presented VLQ branching fractions and are 1570 and 1540 GeV for 100% Formula Presented and 100% Formula Presented, respectively. In most cases, the mass limits obtained exceed previous limits by at least 100 GeV.
