Description
The Higgs boson constitutes a pivotal particle in the Standard Model of particle physics. It was discovered in 2012 by the ATLAS and CMS experiments, and since then its characteristics have been reviewed by both experiments.
This presentation focuses on the CP-structure of the couplings of the Higgs boson to fermions and gauge bosons. After introducing the topic, an overview is provided on the state-of-the-art results on Higgs-CP measurements at the LHC from both the ATLAS and CMS experiment. The recent CMS result on the CP-structure of the Higgs-tau Yukawa coupling will be presented in more detail, including a discussion on the observables, analysis strategy, and methodology.
