利用总积分光度为504 pb−1的ZEUS探测器，在HERA进行了具有孤立高能轻子和大缺失横向动量的事件搜索。结果与标准模型的预测非常吻合。电子-质子与未极化电子碰撞产生单W玻色子的截面测量为0.89−0.22+0.25（stat.）±0.10(syst.)pb。
A search for events with an isolated high-energy lepton and large missing transverse momentum has been performed with the ZEUS detector at HERA using a total integrated luminosity of 504 pb−1. The results agree well with Standard Model predictions. The cross section for production of single W bosons in electron–proton collisions with unpolarised electrons is measured to be 0.89−0.22+0.25(stat.)±0.10(syst.)pb.
