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 $0.91^{+0.26}_{-0.22}$.

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 $|\\kappa_\\text{C}|<3.5$ ($|\\kappa_\\text{C}|<2.7$), the most stringent constraint to date.","name":"Simultaneous probe of the charm and bottom quark Yukawa couplings using $\\mathrm{t\\bar{t}}$H events","url":"https://www.hepdata.net/record/ins2973974?version=1"},"keywords":"P P --> TQ TQBAR H --> BQ BQBAR, SIGNALSTRENGTH, 7000.0, Inclusive, Signal Strength, Integrated Cross Section, Cross Section, Proton-Proton Scattering","name":"mu_sigma_ttHbb","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/166004","version":1}
