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 mak

Abstract We present an analysis of two key sets of data constraining the high x gluon at up to approximate N $${}^3$$ 3 LO in QCD within the MSHT global PDF fitting framework. We begin with LHC 7 and 8 TeV inclusive jet and dijet production at both N

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 thi

Abstract We present the MSHT20qed set of parton distribution functions (PDFs). These are obtained from the MSHT20 global analysis via a refit including QED corrections to the DGLAP evolution at $${{{\mathcal {O}}}}(\alpha ),{{{\mathcal {O}}}}(\alpha

Abstract We investigate the MSHT20 global PDF sets, demonstrating the effects of varying the strong coupling $$\alpha _S(M_Z^2)$$ α S ( M Z 2 ) and the masses of the charm and bottom quarks. We determine the preferred value, and accompanying uncerta

Abstract We present the new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from global analyses of the available hard scattering data. The PDFs are made available at NNLO, NLO, and LO, and supersede the MMHT14 sets. They

Abstract We present the MMHT2015qed PDF set, resulting from the inclusion of QED corrections to the existing set of MMHT Parton Distribution Functions (PDFs), and which contain the photon PDF of the proton. Adopting an input distribution from the LUX

Abstract We present an investigation of the theoretical uncertainties in parton distribution functions (PDFs) due to missing higher-order corrections in the perturbative predictions used in the fit, and their relationship to the uncertainties in subs

Abstract We investigate the impact of the high precision ATLAS and CMS 7 TeV measurements of inclusive jet production on the MMHT global PDF analysis at next-to-next-to-leading order (NNLO). This is made possible by the recent completion of the long-
