The search is performed with data from proton-proton collisions at $\\sqrt{s}=13$ TeV collected by the CMS experiment, corresponding to an integrated luminosity of 138$\\text{fb}^{-1}$. Advanced machine learning techniques are employed for jet flavor identification and event classification. The Higgs boson decay to a bottom quark-antiquark pair is measured simultaneously and the observed $\\text{t}\\overline{\\text{t}}\\text{H}(\\text{H}\\to\\text{b}\\overline{\\text{b}})$ event rate relative to the standard model expectation is $0.91^{+0.26}_{-0.22}$. The observed (expected) upper limit on the product of production cross section and branching fraction $\\sigma(\\text{t}\\overline{\\text{t}}\\text{H})\\mathcal{B}(\\text{H}{\\to}\\text{c}\\overline{\\text{c}})$ is 0.11 ($0.13^{+0.06}_{-0.04}$) pb at $95\\%$ confidence level, corresponding to 7.8 ($8.7^{+4.0}_{-2.6}$) times the standard model prediction. When combined with the previous search for $\\text{H}\\to\\text{c}\\overline{\\text{c}}$ via associated production with a W or Z boson, the observed (expected) $95\\%$ confidence interval on the Higgs-charm Yukawa coupling modifier, $\\kappa_\\text{C}$, is $|\\kappa_\\text{C}|&lt;3.5$ ($|\\kappa_\\text{C}|&lt;2.7$), the most stringent constraint to date.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t1","@type":"Dataset","description":"Upper limits on the signal strength for $\\text{H}\\to\\text{c}\\overline{\\text{c}}$ decays with respect to the standard model expectation of unity.","name":"limits_Hcc"},{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t2","@type":"Dataset","description":"Upper limits on the signal strength for $\\text{t}\\overline{\\text{t}}\\text{H}(\\text{H}\\to\\text{c}\\overline{\\text{c}})$ decays with respect to the standard model expectation of unity.","name":"limits_tHcc"},{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t3","@type":"Dataset","description":"Signal strength and significance for $\\text{t}\\overline{\\text{t}}\\text{H}(\\text{H}\\to\\text{b}\\overline{\\text{b}})$ decays with respect to the standard model expectation of unity.","name":"mu_sigma_ttHbb"},{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t4","@type":"Dataset","description":"Signal strength and significance for $\\text{t}\\overline{\\text{t}}\\text{Z}(\\text{Z}\\to\\text{b}\\overline{\\text{b}})$ decays with respect to the standard model expectation of unity.","name":"mu_sigma_ttZbb"},{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t5","@type":"Dataset","description":"Signal strength and significance for $\\text{t}\\overline{\\text{t}}\\text{Z}(\\text{Z}\\to\\text{c}\\overline{\\text{c}})$ decays with respect to the standard model expectation of unity.","name":"mu_sigma_ttZcc"},{"@id":"https://doi.org/10.17182/hepdata.159997.v1/t6","@type":"Dataset","description":"2D likelihood scans for $\\kappa_{b}$ and $\\kappa_{c}$ for $\\text{t}\\overline{\\text{t}}\\text{H}(\\text{H}\\to\\text{c}\\overline{\\text{c}})$ and $\\text{t}\\overline{\\text{t}}\\text{H}(\\text{H}\\to\\text{b}\\overline{\\text{b}})$.","name":"scan_kappab_vs_kappac"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2973974?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/159997"}],"inLanguage":"en","name":"Simultaneous probe of the charm and bottom quark Yukawa couplings using $\\mathrm{t\\bar{t}}$H events","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2973974?version=1","version":1}
