Abstract

A search for the standard model Higgs boson decaying to a charm quark-antiquark pair, H→cc¯, produced in association with a top quark-antiquark pair (tt¯H) is presented. The search is performed with data from proton-proton collisions at s=13  TeV, corresponding to an integrated luminosity of 138  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 tt¯H(H→bb¯) event rate relative to the standard model expectation is 0.91−0.22+0.26. The observed (expected) upper limit on the product of production cross section and branching fraction σ(tt¯H)B(H→cc¯) is 0.11 (0.13) pb at 95% confidence level, corresponding to 7.8 (8.7) times the standard model prediction. When combined with the previous search for H→cc¯ via associated production with a W or Z boson, the observed (expected) 95% confidence interval on the Higgs-charm Yukawa coupling modifier, κc, is |κc|<3.5 (2.7), the most stringent constraint to date.
