标题： Constraining CP-Violating TGCs and Measuring W-Polarization at OPAL

摘要： 对在189 GeV下产生的半轻子衰变W对中W玻色子的极化进行测量。 纵向和横向极化的W玻色子的速率以及两个W玻色子之间的相关性被研究。 利用W对中轻子衰变的W玻色子的自旋特性来测量CP破坏的三线性规范玻色子耦合。 这些结果与标准模型的预期进行了比较。 显示英文摘要

摘要： A measurement of the polarization of W bosons in semi-leptonically decaying W pairs produced at 189 GeV is presented. Rates of longitudinally and transversely polarized W bosons and correlation between two W bosons are studied. The spin properties of the leptonically decaying W boson in the W pairs was used to measure the CP-violating trilinear gauge boson couplings. These results are compared with Standard Model expectations.
