Abstract
At the designed circular electron-positron collider (CEPC), similar to the hadron collider, the angular distribution coefficients of the decay lepton pair from the produced Z(W) boson in collisions are predicted. Their dependence on cos (cos ) are presented in four different polarization frames. Furthermore, the value of the angular distribution coefficients in different bins of cos are presented in the C-S frame. In comparison with the case at the hadron collider, better accurate measurement for Z(W) is expected because there is less background, and W could be reconstructed from its leptonic decay channel. This works provides a method to precisely test the electroweak production mechanism or some effect induced from new physics in the future measurements at the CEPC.
