中文摘要
电弱混合角sin2\thetaW为标准模型（SM）的一个基本输入参数。LEP与SLC e+e-对撞实验在Z0峰值附近的不对称性观测，给出了现有最精确的有效混合角测量；但轻子末态测量与涉及Z0-夸克中性流耦合的强子道结果存在显著偏离，其相互偏离的程度超出了SM理论预期，并对Higgs质量限制带来了很大的不确定性。我们提出通过Tevatron对撞机D0物理e+e-反应道的电荷前后不对称性AFB分布，精确测量有效弱混合角。初步实验分析验证了我们测量方案是可行的。我们预期基于全部D0数据的AFB与弱混合角测量，将达到远高于LEP Z0强子遍举反应不对称性观测的实验精度,从而检验各种弱混合角测量之间是否存在本质的相互偏离，以实现精确理解标准模型。
