A first determination of the strong coupling $$\alpha _S$$ α S at approximate $$\textrm{N}^3$$ N 3 LO order in a global PDF fit
Abstract We present the first determination of the value of the strong coupling via a simultaneous global fit of the proton parton distribution functions (PDFs) at approximate $$\textrm{N}^3$$ N 3 LO (a $$\textrm{N}^3$$ N 3 LO) order in QCD. This makes use of the MSHT global PDF fitting framework, a...
