Testing Higgs CP Properties at the CEPC with an Additional ISR Parameter

We evaluate the experimental sensitivity to the CP -odd admixture in the standard Higgs boson for the process e + e − → HZ . The analysis is performed assuming the future lepton collider CEPC reference detector operating at $$\sqrt s $$ = 240 GeV with statistics of 5.6 ab –1 . Us...
