| 英文摘要 | To test the standard model (SM) precisely and to look for the clues deviating from SM, a proposal for determining the effective electro-weak mixing angles sin(2) theta efff (particularly f = lept, c, b) is proposed. It is via observing the asymmetries (the forward-backward one A(FB), the left-right one A(LR) and the combined left-right forward-backward one ALRFB) of the doubly heavy-flavored hadrons in the production at a super Z-factory (an e(+)e(-) collider designed with a luminosity as high as possible for modern-day techniques runs around the center-of-mass energy s=mZ). To see the sensitivity, uncertainties as well as the event accumulation precisely, the observables for describing the asymmetries of the produced hadrons are computed numerically with varying effective mixing angles, and based on the result analyses, it is concluded that the proposal may offer an independent complement determination of the effective mixing angles. |
