Description

The next generation collider, CEPC, will operate at sqrt(s)=240 GeV as the Higgs factory to provide a clean environment for precise measurement of Higgs properties. With the expected integrated luminosity of 5.6 /ab, the CEPC will be able to reach the accuracy for Higgs CP property much better than HL-LHC. Thus the anomalous coupling in the presence of BSM physics can be searched with unprecedented sensitivity. More importantly, the coupling can be studied in both ee->Z->ZH and H->ZZ processes to get a better knowledge of q^2-dependence. This talk will summarize the expected results of Higgs CP, and anomalous coupling, fa2 and fa3, with a BDT study of the angular distributions based on MC simulations in CEPC. The sensitivity is significantly improved compared to that from HL-LHC.
