abstract
In this paper we investigate anomalous interactions of the Higgs boson with heavy fermions, employing shapes of kinematic distributions. We study the processes $pp \to t\bar{t} + H$, $b\bar{b} + H$, $tq+H$, and $pp \to H\to\tau^+\tau^-$, and present applications of event generation, re-weighting techniques for fast simulation of anomalous couplings, as well as matrix element techniques for optimal sensitivity. We extend the MELA technique, which proved to be a powerful matrix element tool for Higgs boson discovery and characterization during Run I of the LHC, and implement all analysis tools in the JHU generator framework. A next-to-leading order QCD description of the $pp \to t\bar{t} + H$ process allows us to investigate the performance of MELA in the presence of extra radiation. Finally, projections for LHC measurements through the end of Run III are presented.

Off-shell Higgs boson measurements: Yukawa couplings, self-coupling, compositeness, and width
Using off-shell Higgs production in 138 fb^-1 of 13 TeV CMS data, the collaboration measured Γ_H = 5.1^{+2.0}_{-1.8} MeV, excluded no off-shell production at >5σ, and set the first direct 95% CL lower bound Λ_H > 870 ...

Measurement of the Higgs boson total decay width using the H $\to$ WW $\to$ e$\nu\mu\nu$ decay channel in proton-proton collisions at $\sqrt{s}$ = 13 TeV
CMS measures the Higgs total width as 3.9 +2.7 -2.2 MeV from the ratio of off-shell to on-shell H→WW production, consistent with the Standard Model.

Future Collider Perspectives on Higgs CP Violation
Simulated future-collider studies project that FCC-ee and FCC-hh could constrain CP-violating Higgs EFT couplings 10-100 times more tightly than the HL-LHC, with the proton-proton machine strongest overall.

Measurements of Higgs boson production cross section in the four-lepton final state in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV
At sqrt(s)=13.6 TeV, the H->ZZ->4l fiducial production cross section is measured to be 2.89 +0.53/-0.49 (stat) +0.29/-0.21 (syst) fb, agreeing with the SM prediction 3.09 +0.27/-0.24 fb.
