Abstract:
I will start with a brief summary of what we know about the Higgs boson,
and how we refined our knowledge with recent updated measurements the
CMS and ATLAS collaborations made using the LHC run 2 dataset. Whereas
all measurements of the Higgs boson are so far consistent with the
Standard Model predictions, I will highlight two areas that are worth
keeping an eye on: The couplings of the Higgs boson to fermions, and
searches for additional Higgs bosons.
The measured Higgs boson couplings to fermions tend to be lower than
predicted by the Standard Model. At the same time, these measurements
are experimentally very challenging. I will explain these challenges and
discuss the most recent results. In terms of searches for additional
Higgs bosons, there has been increasing interest in the community
because of a few local excesses that were observed in searches for
additional Higgs bosons. I will put the searches into context and
discuss what we can expect in terms of upcoming analyses.
