The latest results on Higgs boson couplings to fermions and bosons using Run-2 data collected by the ATLAS and CMS experiments are presented. These recent developments include precision measurements performed in the H → ZZ → 4ℓ, H → γγ, and H → WW → 2ℓν decay channels, as well as precise determination of the top-Higgs Yukawa coupling obtained by exploring the ttH and tH production modes. Next, the Higgs boson production at high transverse momentum, via gluon fusion and vector boson fusion mechanisms, is probed by considering the large branching fraction offered by H → bb decays. Finally, experimental evidence for the rare H → γγ∗ → 2ℓγ Dalitz decay and for the coupling of the Higgs boson with fermions of the second generation, via the measurement of H → μμ decays, is reported.

Abstract
The latest results on Higgs boson couplings to fermions and bosons using Run-2 data collected by the ATLAS and CMS experiments are presented. These recent developments include precision measurements performed in the H → ZZ → 4ℓ, H → γγ, and H → WW → 2ℓν decay channels, as well as precise determination of the top-Higgs Yukawa coupling obtained by exploring the ttH and tH production modes. Next, the Higgs boson production at high transverse momentum, via gluon fusion and vector boson fusion mechanisms, is probed by considering the large branching fraction offered by H → bb decays. Finally, experimental evidence for the rare H → γγ∗ → 2ℓγ Dalitz decay and for the coupling of the Higgs boson with fermions of the second generation, via the measurement of H → μμ decays, is reported.
