Abstract
A search is made for a vector-like TT quark decaying into a Higgs boson and a top quark in 13 TeV proton-proton 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\to b\bar{b} and t\to b W \to b q \bar{q}^q′ 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 TT quark at 95% confidence level, depending on the mass, m_T and coupling, \kappa_T of the vector-like TT 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 m_T from a minimum value of 0.35 for 1.07 < m_T < 1.4 TeV to 1.6 for m_T = 2.3 TeV.
