The measurement is performed in the lepton+jets channel of top quark pair production ($\\mathrm{t}\\overline{\\mathrm{t}}$) 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 $400\\,\\mathrm{GeV}$. The data were collected with the CMS detector at the LHC in proton-proton collisions and correspond to an integrated luminosity of $138\\,\\mathrm{fb}^{-1}$. The differential $\\mathrm{t}\\overline{\\mathrm{t}}$ 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 $173.06 \\pm 0.84\\,\\mathrm{GeV}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t1","@type":"Dataset","description":"The particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the XCone-jet mass.","name":"xsec_diff_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t2","@type":"Dataset","description":"Correlations between bins in the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the XCone-jet mass.","name":"correlations_xsec_diff_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t3","@type":"Dataset","description":"The covariance matrix containing the statistical uncertainties of the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the XCone-jet...","name":"covariance_stat_xsec_diff_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t4","@type":"Dataset","description":"The covariance matrix containing the experimental uncertainties of the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the XCone-jet...","name":"covariance_exp_xsec_diff_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t5","@type":"Dataset","description":"The covariance matrix containing the model uncertainties of the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the XCone-jet...","name":"covariance_model_xsec_diff_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t6","@type":"Dataset","description":"The normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the XCone-jet mass.","name":"xsec_diff_norm_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t7","@type":"Dataset","description":"Correlations between bins in the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the XCone-jet mass.","name":"correlations_xsec_diff_norm_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t8","@type":"Dataset","description":"The covariance matrix containing the statistical uncertainties of the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the...","name":"covariance_stat_xsec_diff_norm_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t9","@type":"Dataset","description":"The covariance matrix containing the experimental uncertainties of the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the...","name":"covariance_exp_xsec_diff_norm_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t10","@type":"Dataset","description":"The covariance matrix containing the model uncertainties of the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section as a function of the...","name":"covariance_model_xsec_diff_norm_mjet"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t11","@type":"Dataset","description":"Relative experimental uncertainties of the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the XCone-jet...","name":"uncertainties_exp"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t12","@type":"Dataset","description":"Relative model uncertainties of the particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the XCone-jet...","name":"uncertainties_model"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t13","@type":"Dataset","description":"Relative experimental uncertainties of the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the...","name":"uncertainties_norm_exp"},{"@id":"https://doi.org/10.17182/hepdata.130712.v1/t14","@type":"Dataset","description":"Relative model uncertainties of the normalized particle-level $\\mathrm{t}\\overline{\\mathrm{t}}$ differential cross section in the fiducial region as a function of the...","name":"uncertainties_norm_model"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2175946?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/130712"}],"inLanguage":"en","name":"Measurement of the jet mass distribution and top quark mass in hadronic decays of boosted top quarks in proton-proton collisions at $\\sqrt{s}$ = 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2175946?version=1","version":1}
