摘要

在强子对撞机Tevatron和LHC上进行了各种电弱精度测量。主要是关于W玻色子，顶夸克和希格斯玻色子，以及sin2 ^l_eff的质量。本次演讲涵盖了后者以及使用Drell- Yan衰减进行的其他测量。sin 2 theta^l_eff测量结果的精度大约是LEP和SLD的两倍。Run 2和Run 3数据的LEP和SLD精度有望接近，高亮度LHC数据有望超过。其他测量报告是差分分布和衰减角系数在Drell- Yan事件的全套。

Precision Electroweak Measurements at the LHC and Tevatron

Various electroweak precision measurements are performed at the hadron colliders Tevatron and LHC. The main ones regard the masses of the W boson, top quark and Higgs boson, and sin 2 theta^l_eff. This talk covers the latter and also other measurements carried out using Drell--Yan decays. The results of the sin 2 theta^l_eff measurements have an accuracy of approximately twice that reached at LEP and SLD. The LEP and SLD accuracy is expected to be approached with Run 2 and Run 3 data and surpassed with high-luminosity LHC data. Other measurements reported are the differential distributions and the full set of decay angular coefficient in Drell--Yan events.
