Description

With the increasing precision of PDF determinations, previously small effects require closer analysis. QED effects in PDFs are one such example, typically representing a percent effect, subtleties in their application can result in differences between the global PDF fitting groups. We analyse these and present the current status, as well as impacts on Higgs production cross-sections.
