A bstract A search for T and Y vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of 13 TeV and decaying into Wb in the fully hadronic final state is presented. The search uses 139 fb − 1 of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying W boson with large Lorentz boost and a b -tagged jet, which are used to reconstruct the invariant mass of the vector-like quark candidate. The main background is QCD multijet production, which is estimated using a data-driven method. Upon finding no significant excess in data, mass limits at 95% confidence level are obtained as a function of the global coupling parameter, κ . The observed lower limits on the masses of Y quarks with κ = 0 . 5 and κ = 0 . 7 are 2 . 0 TeV and 2 . 4 TeV, respectively. For T quarks, the observed mass limits are 1 . 4 TeV for κ = 0 . 5 and 1 . 9 TeV for κ = 0 . 7.
