Updates of PDFs in the MSTW framework

TL;DR

This paper discusses recent updates to parton distribution functions within the MSTW framework, incorporating new data and methodological improvements, resulting in a new, nearly finalized PDF set.

Contribution

It introduces theory and procedural enhancements and integrates recent LHC data into the MSTW PDF framework, advancing the accuracy of the PDFs.

Findings

New PDF set is close to finalization

Inclusion of recent LHC data improves PDFs

No significant changes expected to preliminary PDFs

Abstract

I present results on updates on PDFs which are obtained within the general framework which led to the MSTW2008 PDF sets. There are some theory and procedural improvements and a variety of new data sets, including many relevant up-to-date LHC data. A new set of PDFs is very close to being finalised, with no significant changes expected to the preliminary PDFs shown here.
