  "description": "<p>A measurement of the jet mass distribution in hadronic decays of Lorentz-boosted top quarks is presented. The measurement is performed in the lepton + jets channel of top quark pair production (    $\\text{t}\\overline{\\text{t}}$  ) events, where the lepton is an electron or muon. The products of the hadronic top quark decay are reconstructed using a single large-radius jet with transverse momentum greater than 400    $\\phantom{\\rule{0.166667em}{0ex}}\\text{Ge}\\phantom{\\rule{-0.80002pt}{0ex}}\\text{V}$  . The data were collected with the CMS detector at the LHC in proton-proton collisions and correspond to an integrated luminosity of 138    $\\phantom{\\rule{0.166667em}{0ex}}{\\text{fb}}^{-1}$  . The differential     $\\text{t}\\overline{\\text{t}}$   production cross section as a function of the jet mass is unfolded to the particle level and is used to extract the top quark mass. The jet mass scale is calibrated using the hadronic W boson decay within the large-radius jet. The uncertainties in the modelling of the final state radiation are reduced by studying angular correlations in the jet substructure. These developments lead to a significant increase in precision, and a top quark mass of     $173.06\u00b10.84\\phantom{\\rule{0.166667em}{0ex}}\\text{Ge}\\phantom{\\rule{-0.80002pt}{0ex}}\\text{V}$  .</p>",
