论文摘要
我们介绍了W-Boson质量平均项目的当前状态，该项目旨在结合Tevatron和LHC测量值。提出了方法以准确评估PDF和其他建模变化对现有测量的影响。基于这种方法，可以将测量值校正为常见的建模参考和相同的PDF，然后以定量方式将PDF相关性结合在一起。我们讨论了组合程序以及改进在W-Boson生产和衰减的理论描述中的影响。
We present the current status of the W-boson mass averaging project, an ongoing effort aimed at combining Tevatron and LHC measurements. Methods are presented to accurately evaluate the effect of PDFs and other modelling variations on existing measurements. Based on this approach, the measurements can be corrected to a common modelling reference and to the same PDFs, and subsequently combined accounting for PDF correlations in a quantitative way. We discuss the combination procedure, and the impact of improvements in the theoretical description of W-boson production and decay.
