Higgs boson CP property measurements at the ATLAS experiment

While the Standard Model predicts that the Higgs boson is a CP-even scalar, CP-odd contributions to the Higgs boson interactions with vector bosons and fermions are presently not strongly constrained. A variety of Higgs boson production processes and decays can be used to study the CP nature of the Higgs boson interactions. This talk presents the most recent results of such analyses by the ATLAS experiment, based on pp collision data collected at 13 TeV
