Combination of aN${}^3$LO PDFs and implications for Higgs production cross-sections at the LHC

Thomas Cridge, Lucian A. Harland-Lang, Jamie McGowan +14

We discuss how the two existing approximate N${}^3$LO (aN${}^3$LO) sets of parton distributions (PDFs) from the MSHT20 and NNPDF4.0 series can be combined for LHC phenomenology, both i…
