Status of the W-boson mass averaging project
November 22, 2022
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.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
