A search is made for a vectorlike T quark decaying into a Higgs boson and a top quark in 13 TeV protonproton
collisions using the ATLAS detector at the Large Hadron Collider with a data sample corresponding
to an integrated luminosity of 139 fb−1. The Higgs-boson and top-quark candidates are identified in the
all-hadronic decay mode, where H → b¯b and t → bW → bq¯q0 are reconstructed as large-radius jets. The
candidate Higgs boson, top quark, and associated B hadrons are identified using tagging algorithms. No
significant excess is observed above the background, so limits are set on the production cross section of a
singlet T quark at 95% confidence level, depending on the mass mT and coupling κT of the vectorlike T
quark to Standard Model particles. In the considered mass range between 1.0 and 2.3 TeV, the upper limit
on the allowed coupling values increases with mT from a minimum value of 0.35 for 1.07 < mT < 1.4 TeV
to 1.6 for mT ¼ 2.3 TeV.
