The contribution will review recent ATLAS and CMS measurements of Higgs production in association with two top quarks (ttH) and single top quark (tH), emphasizing latest Run-2 and early Run-3 results and combination where available, and the resulting constraints on the top–Higgs coupling, on CP violating contributions, and possible deviations from the Standard Model. (17' presentation + 5' discussion)

An important aspect of the Higgs boson physics programme at the LHC is to determine all the properties of this particle, including its width, which is directly linked to its lifetime. Deviations from the SM prediction of a narrow resonance might hint about unknown decays of the Higgs boson. This presentation will discuss the latest developments in measurements of the Higgs boson width, with...

I point out that Yukawa interactions of light quarks with the Higgs boson are imprinted as unique azimuthal modulations in the density of fragmentation hadrons relative to the Higgs $p_T$. I introduce Yukawa Fragmentation Asymmetries (YFAs), cut-and-count interference observables that are linearly proportional to real (Standard Model) or CP-odd Yukawa couplings $y_q$, respectively. The...
