本文研究了在MZ ~ 2附近Q ~ 2处轻子-核子深度非弹性散射中孤立单个电弱结构函数的可能性。利用截面对轻子荷和纵向极化λ的依赖性,我们发现最确定的结果来自于对σ+(−λ)±σ−(+λ)的测量。如果λ可以调整到与sin 2 θ相关的值约为0.2,则问题可以大大简化。导出了新的夸克-部分子模型关系。
The possibility is studied of isolating single electroweak structure functions in deep inelastic lepton-nucleon scattering atQ2aroundMZ2. Utilizing the cross-section dependence on the lepton charge and longitudinal polarization λ it is shown that the most-conclusive results follow from measurements of σ+(−λ)±σ−(+λ). Considerable simplifications of the problem are possible if λ can be tuned to sin2θ dependent values of about 0.2. New quark-parton model relations are derived.
