This analysis will use the complete run-2 dataset from the LHC to make the first measurement of off-shell W boson production at high scales. The measurement in both the W+ and W- channels will also be performed double-differntially in mT and |\eta| and allow a determination of the W charge asymmetry. The data call offer contraints on the flavour decomposition of the proton at high x. In addition the measurements will offer a unique contraints on the oblique parameters which parameterise the effects of new physics in a general effective field theory approach for dimension-6 operators.

该分析将使用LHC的完整运行2数据集，首次测量高尺度下的离壳W玻色子产生。W+和W-通道中的测量也将以mT和|谢塔|并允许确定W电荷不对称性。数据调用提供了在高x质子的味分解的约束。此外，测量将提供一个独特的约束的斜参数化的影响，新的物理在一个通用的有效场论方法的6维运营商。
