Description
We will review the extension of the MSHT20 PDFs to approximate N3LO order and the consequences for phenomenology. We first describe the inclusion of the known N3LO information and the parameterisation of the remaining missing N3LO contributions, as well as the determination of the theoretical uncertainties from missing pieces and higher orders and their interpretation. We then examine the impact on the PDFs as well as on predicted cross-sections. We will also comment on updates to the aN3LO PDFs.
