The Higgs Boson at CMS: from Top to Bottom — •Matthias Schröder — KIT

In the Standard Model of particle physics, the Higgs boson is deeply related to the mechanism that creates the masses of the elementary particles. Thus, a precise measurement of the Higgs boson properties offers a unique probe of this mechanism and plays a crucial role in testing the predictions of the Standard Model or revealing potential new physics.

The Higgs boson mass and its couplings to the electroweak gauge bosons have been established early after its discovery during LHC Run 1, but high sensitivity to the couplings to fermions is achieved only now with the large amount of data collected at 13 TeV centre-of-mass energy during LHC Run 2. This led to the recent observations of the Higgs boson couplings to tau leptons and top and bottom quarks, which mark crucial steps in understanding the mechanism of fermion-mass generation.

In this presentation, the latest Higgs boson measurements performed with the CMS experiment will be reviewed, with special focus on the couplings to fermions. Furthermore, prospects for future measurements at the High-Luminosity LHC will be discussed.
