dc.description.abstractThe first measurement of the CP structure of the Yukawa coupling between the Higgs boson and ? leptons is presented. The measurement is based on data collected in proton-proton collisions at ? s = 13 TeV by the CMS detector at the LHC, corresponding to an integrated luminosity of 137 fb?1 . The analysis uses the angular correlation between the decay planes of ? leptons produced in Higgs boson decays. The effective mixing angle between CP-even and CP-odd ? Yukawa couplings is found to be ?1 ± 19? , compared to an expected value of 0 ± 21? at the 68.3% confidence level. The data disfavour the pure CP-odd scenario at 3.0 standard deviations. The results are compatible with predictions for the standard model Higgs boson.es_ES
