An investigation of the $$\alpha _S$$ and heavy quark mass dependence in the MSHT20 global PDF analysis (2021)
Journal Article
Cridge, T., Harland-Lang, L., Martin, A., & Thorne, R. (2021). An investigation of the $$\alpha _S$$ and heavy quark mass dependence in the MSHT20 global PDF analysis. The European Physical Journal C, 81(8), Article 744. https://doi.org/10.1140/epjc/s10052-021-09533-7

We investigate the MSHT20 global PDF sets, demonstrating the effects of varying the strong coupling αS(M2Z) and the masses of the charm and bottom quarks. We determine the preferred value, and accompanying uncertainties, when we allow αS(M2Z) to be a...

Parton distributions from LHC, HERA, Tevatron and fixed target data: MSHT20 PDFs (2021)
Journal Article
Bailey, S., Cridge, T., Harland-Lang, L., Martin, A., & Thorne, R. (2021). Parton distributions from LHC, HERA, Tevatron and fixed target data: MSHT20 PDFs. The European Physical Journal C, 81(4), Article 341. https://doi.org/10.1140/epjc/s10052-021-09057-0

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 are obta... Read More about Parton distributions from LHC, HERA, Tevatron and fixed target data: MSHT20 PDFs.

Dynamics of diffractive dissociation (2021)
Journal Article
Khoze, V., Martin, A., & Ryskin, M. (2021). Dynamics of diffractive dissociation. The European Physical Journal C, 81(2), Article 175. https://doi.org/10.1140/epjc/s10052-021-08953-9

We describe a QCD based model which incorporates the main properties of the inclusive particle distributions expected for diffractive processes, including the diffractive dissociation at high energies. We study, in turn, the total cross section, σtot... Read More about Dynamics of diffractive dissociation.
