Approximate N $$^{3}$$ 3 LO parton distribution functions with theoretical uncertainties: MSHT20aN $$^3$$ 3 LO PDFs
Abstract We present the first global analysis of parton distribution functions (PDFs) at approximate N $$^{3}$$ 3 LO in the strong coupling constant $$\alpha _{s}$$ α s , extending beyond the current highest NNLO achieved in PDF fits. To achieve this, we present a general formalism for the inclusion...
