On the basis of the study of inclusive hadronic events, two methods are adopted to determine the number of produced ψ(2S) events collected by BES in 2001-2002 run, which is 14:0 ? 106 with the uncertainty of 4%.

A 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.
