Probing new physics with the Higgs-vector-boson coupling with the ATLAS detector
Thirteen years after the discovery of the Higgs boson, the LHC program has entered a precision era in the study of this fundamental particle, which couples to all massive states in the Standard Model. In particular, the Higgs-vector-boson interaction provides a powerful window for precision tests, as potential deviations from the Standard Model may arise from charge-parity (CP) violating effects. Such CP violation is a key ingredient required to explain the matter–antimatter asymmetry of the Universe. This seminar will present the Effective Field Theory framework used to systematically probe CP-violating Higgs couplings, and will discuss recent experimental and theoretical advancements that enhance the precision of Higgs measurements using the Run-2 dataset collected by the ATLAS detector at a center-of-mass energy of 13 TeV.
