Measurement of off-shell production of W bosons at high transverse mass at 13 TeV and contraints on new physics

该分析将使用来自大型强子对撞机的完整run-2数据集，在高尺度上首次测量离壳W玻色子的产生。W+和W-通道的测量也将在mT和|\eta|中进行双差分测量，并允许确定W电荷不对称。数据调用对质子在高x下的风味分解提供了约束。此外，测量将对斜向参数提供独特的约束，斜向参数在6维算子的一般有效场论方法中参数化新物理的影响。

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.
