Interference effects on Higgs mass measurement in $e^+e^-\to H(\gamma\gamma) Z$ at CEPC
high luminosity Circular Electron Positron Collider (CEPC) as a Higgs Factory will be helpful to the precision measurement of the Higgs mass. The signal-background interference effect is carefully studied for the Higgs diphoton decay mode in the associated Z boson production at the future?e+e??colliders at energy?246GeV. The mass shifts go up from about?20MeV?to?50MeV?for the experimental mass resolution ranging from?0.8GeV?to?2GeV.
