Description

We consider the extension of the MSHT20 PDFs to an approximate N$^3$LO order. We describe the parameterisation of the missing N$^3$LO contributions and the determination of the theoretical uncertainties and their interpretation. We examine the impact of further data sets and look at the stability of predicted cross sections.
