Description
I will outline the current status of parton distribution functions in the context of the LHC and future colliders. This will include the developments, state of the art and consequences for phenomenology now and in the future, emphasising their importance for the current and future particle physics program. In this context I will review progress in the MSHT PDF determination, including the world first approximate N3LO PDFs with a novel approach for the inclusion of missing higher order theoretical uncertainties in QCD. In addition I review the first PDF extraction of the strong coupling at aN3LO, QED and electroweak effects on PDFs, and methodological developments, amongst other aspects.
