本文给出了费米实验室Tevatron对撞机D0探测器在质心能量为1.96 TeV的事件中有效弱混合角参数的测量结果，并与积分光度的测量结果相对应。的测量值进一步与事件中的D0测量结果相结合，得到。这一综合结果是强子对撞机单次实验中最精确的测量结果，也是利用夸克与轻夸克耦合的最精确的测定结果。
We present a measurement of the effective weak mixing angle parameterinevents at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron Collider and corresponding toof integrated luminosity. The measured value ofis further combined with the result from the D0 measurement inevents, resulting in. This combined result is the most precise measurement from a single experiment at a hadron collider and is the most precise determination using the coupling of theto light quarks.
